Camera

Target

LED reflection/imprint is seen by camera�

Due to the differences in solder ball shape and size their appearance is inconsistent�

Multi angle diffused light is radiated around the inner surface to give uniform illumination�

The multi angle diffused light results in consistent illumination of all the solder balls and an overall brighter image�

When the light to target distance is far the multi angled diffused light is applied across the whole of the target� This creates a uniform illumination effect without irregularities similar to using a dome light source�

When the light to target distance is short the light emitted at a shallow angle reflects directly back to the camera� This causes the edges of the target to be highlighted creating an effect similar to using a low angle light source�

Edge enhancement illumination equivalent to low angle lighting

Since LEDs are mounted at high density (narrow pitch), uniform high intensity light is generated�

To obtain maximum diffusion effect, the whole area of the diffusion plate has a matte finish�

Construction and imaging examples

08

The inside of the ring light is divided into eight segments� Depending on the settings of the LumiTrax function, the eight segments of the ring can be lit individually or the ring can be set to four segments that are lit individually� When the LumiTrax function is not in use, these lights can be used as high-intensity lights in which all the segments lit�

Imaging examples using the LumiTrax function

1/4 of the ring is lit.

Chip inspection on a metal surface

Factors such as remaining cleaning agent, dirt, and hairline fractures are cancelled so that only deep defects such as scratches and chips are detected�

Chip inspection on a printed surfaceStrobe lighting with a high-output LED

Images in which only the chips are extracted are created without being affected by the complex printed background�

Printed character inspection on a film surface

Glare, which affects inspections negatively, is eliminated to enable stable inspections�

LumiTrax imaging is supported by the XG-8000/CV-X200 Series� When not performing LumiTrax imaging, these lights can only be used with all the segments lit� For detailed information on device combinations, contact your nearest KEYENCE office�

Lighting, camera, and inspection algorithm all in one unit

These lights can be used with “LumiTrax,” our completely new imaging method� They can also be used as high-intensity lighting with a light intensity approximately three times that of conventional lights�

Bar light illumination techniques

Bar lights can be used to apply a strip of light along a target edge� Depending on the angle of the light and the camera, the bar light can be used to enhance or reduce specular reflection from a target� For highlighting a feature with specular reflection (such as the tip of a pin) the direct reflection of light has to come back into the camera� For removing specular reflection (sometimes referred to as hotspots) the direct line of reflection needs to be away from the camera�

ApplicationDome light illumination techniques

A dome light radiates indirect light at various angles due to the LED’s being mounted at the surface and shinning up into the dome� When standard lighting is used direct reflection from the part can result in a hot spot (halation) causing inspection and reliability problems� As the dome light diffuses at all angles a target with a complicated shape can be uniformly lit with diffuse light from all angles eliminating hotspots� As the target is uniformly lit a stable reliable inspection can be easily setup�

Due to the shiny surface and inconsistent shape the print cannot be recognised�

Due to the curved glossy surface the light being used creates a hotspot (halation)�

As the dome lights from all angles the light is uniform across the curved areas�

Dome Light

The dome light removes shadows and hotspots (halation) created with standard lighting.

These are the optimal lights for workpieces that easily create glare such as metal surfaces and films�

Hot spots (halation) means filaments cannot be clearly seen�

Some edge points are unclear and blend into the background�

Hot spots and inconsistent contrast occurs across the part making edge detection unstable�

A foreign object easily blends into the fabric, especially if it is thin or of a similar colour�

The filaments are clearly shown, enabling clear detection of any breaks�

Complicated outlines and edge points are clearly shown with a sharp contrast�

The backlight ensures a silhouette of the target creating a high contrast edge�

The extra density from the presence of a foreign object ensures a shadow is created when a back light is used�


Back lights enable crisp silhouetting of target profiles to enable high precision measurement or part differentiation.

These lights can also be used as reflected lights with large lighting areas�

CA-DS Series

Back LightsThin profile complete surface illumination

Standard front lighting can cause inconsistent and low contrast of a targets features due to shape, colour and surface finish� Using a backlight ensures transmission of the light through the target into the camera� If the target is opaque a silhouette is generated creating a strong contrast and outline for stable inspection� Even if a target is transparent it may have a range of densities to it (such as layered material or liquid in a bottle)� Contrast can still be achieved through the changes in the absorption and transmission of light in the target�

Wavelength conversion sheet features

Wavelength conversion mechanism

Combining the wavelength conversion sheet, blue LED light, and blue cut filter create an absolutely new piece of light technology that can be used to realise back light images with reflected light�

16

Industry’s first

This is the image obtained when the white workpiece is placed on top of the wavelength conversion sheet and the white sheet�

This is the image obtained when the blue light is emitted� The white background and the white sheet are imaged in blue� The waveform conversion sheet converts the blue light to an orange colour tinged with red and reflects this colour�

The blue cut filter cuts out the reflected light in the blue range, and only the light from the wavelength conversion sheet enters the lens� In this way, an image like that captured of the white workpiece with a back light is obtained�

In addition, install a blue cut filter on the lens.

Making it possible to use back lights in locations where it was only possible to install reflected lights.

Some inspections are normally stabilised through the use of back lights� However there are situations where back lights cannot be installed, possibly due to a lack of installation space or an inability to wire around moving parts� In these cases, back lights can be emulated by attaching a wavelength conversion sheet and installing blue reflected lights�

AlignmentIt’s difficult to route cables when embedding light in a moving stage, but there are times when the contrast with just reflected light is insufficient� By using the wavelength conversion sheet, it’s possible to realise back light images without any wiring, which makes stable detections possible�

Liquid surface inspectionAssume that there is no space to install a back light when performing liquid surface inspections at a filling machine and that reflected light has to be used instead� Even if the light is installed in a narrow space, back light images can be realised by wrapping the wavelength conversion sheet around the rotating object�

The contrast for the alignment mark is insufficient, so stable detection is not possible�

Due to the effect of the reflection from the workpiece surface, it is not possible to obtain a stable view of the liquid surface�

The contrast obtained is equivalent to that of images captured with back lights, which improves the alignment precision�

There may be foreign substances on the surface of the wavelength conversion sheet� However, even if such substances are present, the product is still within the inspection standards, and these substances do not indicate that the product is defective�

Only the liquid surface is clearly imaged as a back light image, which makes it possible to perform stable liquid surface inspections�

Weight Approx. 20 g (including the peelable sheet)

*1 This is the value only for the special wavelength converting material�

*2 The wavelength converting material is pasted on the entirety of the A4-sized surface� There are no margins�

*3 Adhesive strength: 9�4 N/25 mm 30 minutes after application, 10�8 N/25 mm 24 hours after application

• In environments with low or high temperatures, the adhesive strength and the maintenance of adhesion decrease, which makes it easy for the sheet to peel off�

• The sheet’s adhesive capability and capability to be peeled off repeatedly may be affected by the shape of the object that the sheet is affixed to as well as by the usage environment and conditions� Also, if there are concerns regarding the sheet being peeled off or becoming dirty, the sheet can be used with a cover made of glass, acrylic, or a similar material in place over top of it� In this situation, the brightness may be slightly attenuated due to the glass or other material�

• If the surface is dirty, wipe it clean with a soft cloth to which a neutral cleaning solution with no abrasive has been applied�• Scissors or a box cutter can be used to cut the sheet to a different size�

Edges are not clear as diffuse and specular light is received by the camera�

Marking is unclear�

Various light components are reflected at all angles causing inconsistent images from part to part�

Specular reflection causes lights to appear on the glass surface�

The recessed areas diffuse light so they appear dark and the edges can be easily identified�

The edges of the marking are clearly defined�

The change from curved to flat is clearly identified and the flat area is highlighted well to the camera�

Uniform illumination is possible�

This illumination style provides high contrast, because only specular-reflection light is reflected back to the camera, while diffuse light from a recess or edge is not.

These lights are effective when inspecting mirror surfaces and glossy surfaces and when distinguishing between objects according to differences in glossiness�

CA-DX Series

Coaxial Lights (Vertical)Coaxial vertical illumination emits light on the same axis as the camera and lens.

The co-axial light transmits light from the side onto a half way mirror� The mirror reflects the light onto the target�Specular reflected light is allowed to pass back up to the camera whereas as diffuse reflected light from the target is rejected� This in turn causes a contrast at the edge points of a target�In addition, the further the light is from the target the greater the rejection of diffused light becomes, creating greater image contrast and definition�

The image to the left displays the relative brightness across a 10000 point grid for the CA-DP Series� Although the intensity varies with each model type, the associated illumination distance and relative brightness across the area are consistent�The brightest areas (shown in red) are considered 100% relative intensity and the dullest areas (shown in green) are considered 0% relative intensity� The images display the intensity differential across the area� By comparing the changes in the intensity differential for different lighting heights (LWD) the ideal lighting range can be realised with the relative brightest points being 100%�

Surface/edge chipTypically, surface and edge defects are hard to detect with standard lighting as there is little contrast change� The low angle light highlights the physical change in the target making detection possible�

With standard lighting With standard lightingWith low angle illumination With low angle illumination

Camera/ light arrangement

Low angle lighting provides direct light at a shallow angle onto the target� Typically inspection of the edge of a target or physical flaws on the surface are hard to detect with standard direct lighting� As the direction of the light is almost parallel to the surface any change in surface height deflects the normal path of light to the camera, subsequently highlighting the change�

Low angle light illumination techniques

Dimensions Unit: mm

Low-angle illumination provides a high contrast to an edge, recess or a protrusion against their normal background.

These lights make just the edges and contours of the target stand out by shining LED light at shallow angles and nearly horizontally�

Illumination of a target can be freely controlled, by changing the angle and choosing which sides of the target should be lit.

These units are made of lights in four directions whose angles, light intensities, and lighting timings can be set separately, which makes it possible to perform previously difficult inspections�

CA-DQ Series

Square Lights (Direct)The square lights are made up of four bars lights, which can be individually controlled and positioned.

Application

Inspection of sealantThe presence/absence of sealant can be checked across the whole target area� By adjusting the installation distance and angle the whole target can be uniformly lit�

Technical Guide

Selection of lighting for line scan cameras

When using line scan cameras, it is not necessary to illuminate the entire target� Therefore, images can be taken using a narrow area of the part� Illumination of the target can be classified in three ways�

Diffuser plate and polarising plate

Use diffuser plates and polarising plates to effectively utilise light for an application�

24

Diffuser plateDiffuser plates are sheets or films that uniformly diffuse light to the entire surface� Ground glass used to be popular, but plastics are more common now� In recent years, diffuser plates are used as a part of backlights mounted on the rear of liquid crystal display panels�

Defective areas will appear as black since light does not return to the camera if there are flaws or dents�

Defective areas will appear as white by light applied to burrs and convex flaws reflecting towards the camera�

This is a method often used for measuring dimensions and for inspecting foreign objects on a sheet� Transmissive lighting will enhance the edges, and blockage of light will cause foreign objects to appear black when inspecting for foreign objects�

• Continuous use of LED illumination at high temperature and high humidity accelerates light intensity reduction and deterioration�

• Reduce heat emission from illumination�

If LED illumination is used at the maximum light intensity, illumination emits a large amount of heat, which will affect the service life� It is recommended that the limit function should be turned on, or the light adjustment trimmer should be set to approx� 40 to 60%� (Standard feature of CA-DC100)

It is recommended that the external ON/OFF switching function should be used to strobe lights in synchronisation with image capturing�* LED’s do not deteriorate or burn out like

normal lights when pulsed at a high ON/OFF frequency�

Installation of a cooling air blower and fan, and using mounting brackets with high heat conductivity are effective�

Use LED illumination in an environment that ensures easy heat

radiation and cooling.

Use the limit function and the light adjustment trimmer.

Turn on LED illumination only when capturing images.

Specular reflection and diffuse reflection

Selecting correct illumination based on colour

Illumination wavelength characteristics

Target surface conditions (colour, glossiness, surface finish, etc�) vary

depending on the type of target� Glossiness is an important point to keep in

mind when you set an illumination angle for your lighting� When light with

equal intensity is applied to a glossy and matte target at the same angle,

specular-reflection light components are intensified with the glossy area,

while diffuse-reflection light components are intensified with the matte area�

By adjusting the illumination or camera angle based on this characteristic,

a glossy part can be intensified, or darkened helping to ensure stable

repeatable inspection of a target�

28

Effective use of illuminationTechnical Guide

A red candy wrapper is placed in a brown carton box� The images below show the contrast levels

when white, red and blue illumination is used�

To enhance target features the scatter ratio of the light can be used to good effect�

Due to blues short wavelength its scattering ratio is high unlike red light� Hence

blue lighting can enhance scratches and surface flaws that may not be shown with

red lighting�

In the examples to the right the effect of using blue and red light can be clearly seen� Depending on the application, blue light might

be ideal to enhance flaws and create a reliable inspection� Whereas red light might be a better choice to eliminate surface finish to

help prevent a false reject when inspecting a part�

* Relative light intensity change for a 1:4 ON/OFF time ratio.

CCD camera sensitivity

Continuous vs strobe LED lighting

A CCD’s sensitivity characteristics are similar to those of the human eyes, providing highest detection

sensitivity around 500 nm (blue light wavelength)�

Therefore, when red light and blue light with the same intensity are applied to the same target, blue light

produces a brighter image� This functionality can be put to good use when a bright image is needed in

an application that requires a large depth of field or high shutter speed�

Being able to keep the light off when not required can significantly increase the service life of the light� One

advantage to using LED illumination in machine vision is that high frequency ON/OFF switching does not result

in damage to the LED element� For example, when the ON/OFF ratio time is 1:4 (e�g� 10 ms vs 40 ms) then the

service life can be expected to be 5 times that when used in continuous operation�

Depending on the application, there may be cases where infrared is used as the lighting� Infrared light cannot

be seen by the human eye, but general CCDs have sensitivity that enables them to receive infrared light�

Therefore, they can perform infrared imaging� However, colour cameras are equipped with filters that cut

infrared light in order to enable these cameras to reproduce the same colours that can be seen by humans�

Therefore, these cameras cannot perform infrared imaging� Use a monochrome camera to enable the use of

infrared light� In addition, we recommend using the CA-LHE/LHR Series lenses when using infrared light� These

lenses have relatively high infrared transmission ratios compared to other lenses�

* We do not sell infrared LED lights� For details, contact KEYENCE

If colour and surface reflectivity vary depending on workpiece type, light intensity adjustment should be conducted every time the workpiece type is changed� Users

may also change the shutter speed, however this may not be suitable depending on the line speed of the application and other illumination factors� The ideal thing to

do would be to change the illumination intensity according to the target� With the CA-DC21E the light intensity can be automatically changed as part of the vision

program� Preset optimal values can be set, stored and referenced depending on the target being inspected� Making product switch over quick and easy�

It’s possible to turn on the light only when capturing images (strobe lighting)�

Unlike fluorescent and halogen lights, the light is not degraded when repeatedly

turned on and off, which provides peace of mind� Only turning the light on when

necessary makes it possible to reduce the heat generated by the LED, which

reduces degradation�

Compared to fluorescent lights and other lighting devices (which

are restricted to vacuum tube shapes), this device is itself made of

small LEDs, which makes it possible to implement the optimal

exposure format—such as direct, diffuse reflection, specular

reflection, low angle, and transmitted—and exposure area for

different workpieces by installing the device in different ways�

The vacuum tubes of fluorescent and halogen lights are full of gas� These

constructions are weak against vibration and impact due to the presence of

components such as filaments� In comparison, an LED is itself a light-emitting

element, which eliminates the need for light-emitting mechanisms and lighting

circuits� This leads to an exceedingly small amount of mechanical malfunctions

and defects� Therefore, it can be said that LEDs have higher reliability than

fluorescent and halogen lights when it comes to implementation in actual lines�

Good switching characteristics

Strobe lighting example

Configurable exposure format Excellent impact resistance

Connecting the CA-DC21E eliminates the need for wiring, which enables strobe lighting�

• Heat causes the light intensity to decrease, which leads to device degradation�

• Using the device at a high temperature shortens its service life�• Using the device to perform continuous lighting makes the light

source hot�

• Use the device with strobe lighting�• Install a fan to blow air over the device, thereby promoting the

radiation of heat�• Lower the power supply’s light adjustment trimmer�

LEDs are said to have a service life of approximately 30000 hours� This is

approximately 15 to 30 times the service life of fluorescent and halogen lights

(see the following chart)� The service life of LED elements depends on the time

that the light is lit� Therefore, the service life can be even further extended by

controlling the lit time through external control or similar means� This makes it

possible to greatly reduce the cost and effort attributed to light source

replacements and other maintenance after installation�

CA-LHR Series

High Resolution, Low Distortion LensProviding ultimate imaging performance for 2 and 5 megapixel cameras

Special optical design and construction

The CA-LHR Series provides a resolving power of 200 cycles/mm at the centre of the lens and 140 cycles/mm on the periphery of the lens, which is twice or higher the performance of conventional high-resolution lenses� This makes it possible to obtain high-contrast images and perform stable inspections of the dimensions and appearance of targets�

Minimum working distance By using special low-scattering glass, we have achieved a working distance of 0�1 m for all models� This makes it possible to use the lens to the extent of its capabilities over a wide range without needing a close-up ring�

The same resolution is obtained in the centre of the image, but the resolution is worse in the periphery of the image due to the effect of the close-up ring�

Minimum working distance When compared to standard lenses the CA-LH Series has a significantly reduced minimum working distance� This means that one lens can easily accommodate for a range of different target heights without the need for close up rings or troublesome change overs�

Lowest distortion in its class

With an original optical design, the CA-LH Series drastically eliminates distortion� This is of great significance when using machine vision for dimensional measurement or other applications that need high precision and performance� Distortion is reduced to 0�01% or less�** With CA-LH50 on 1/3" CCD size

Using a floating mechanism that moves the front lens and rear lens individually, the CA-LH Series provides consistent optical performance across a wide range of working distances to maintain a sharp image� Contrast is also improved in comparison with standard lenses� Even targets with low contrast differences can be resolved effectively without components being blended together�

The industry’s first fixed aperture replacement methodBy using fixed apertures, we have eliminated the problem of foreign contamination occurring due to the aperture drive section rubbing against another surface when the lens is subjected to vibrations� At the same time, the ability to replace aperture plates ensures support for different situations� Because the aperture values are fixed, it is easy to ensure that multiple units all use the same F-stop�

After adjusting the lens extending amount, use the red ring to fix the focus� The construction of this fixing section differs from the pin-point operation of a screw and performs fixing with a wide area, which makes it difficult for looseness to occur� The sufficient focus adjustment width enables both a minimum working distance of 0�1 m and ease of use�

VPR equipped With conventional telecentric macro lenses, the selections were limited and depended on the characteristic optical magnifications of the lenses� The VPR (Variable Pixel Resolution) mechanism not only makes it possible to select lenses intuitively according to the pixel resolution but also brings a level of freedom to the range over which optical magnification can be adjusted�* These lenses are designed with optical magnification to match 5 megapixels (3�45 μm/pixel) and 2 megapixels (4�4 μm/pixel)�

Ultra high-resolution design

These lenses have been designed with consistently high resolution not only in the centre of the image but on its periphery as well� Even with a unit cell size of 3�45 μm/pixel, every part of the screen exhibits high resolution and contrast�

Distortion free

42

All models have a TV distortion of 0�02% or lower� This reduces distortion to 0�25 pixels or less over the entire image even for a 5 megapixel camera� These lenses are the perfect choice for a wide range of applications from dimension measurement to alignment�

The entire screen is free of distortion, and high-resolution images can be obtained�

CA-LMHR

Even for the most detailed part of the chart, sufficient contrast between the white and black lines is obtained�

CA-LM

Because the resolution is insufficient, the contrast is extremely low, which makes it impossible to sufficiently recognise the edges�

One of the ideal forms of telecentric macro lenses

The distortion-free performance of this lens and its VPR (Variable Pixel Resolution) mechanism make it easy to capture ideal images�

Polarisation principle

Without polarising filterThere is an imprint of the ring light�

With polarising filterThe light imprint is reduced�

Light (1) is polarised with polarisation filter A so only horizontal light (2) is

transmitted to the target� Because polarisation filter B is set to accept vertical

light only, the specular light (3) reflected from the film surface is rejected�

However, the diffuse reflected light (4) from the target has a vertical

component (5) that is allowed to pass through B to the camera�

The focal range of the lens can be changed by using close-up rings between the camera and the lens�For the thickness to use, see the FOV chart for each lens�The set contains rings with five different thicknesses: 0�5 mm, 1 mm, 5 mm, 10 mm, and 22 mm�

• The protective filter ensures a long service life of the lens by preventing

damage during lens maintenance�

• During lens maintenance, all that needs to be done is replace the protective

filter, which can be washed with water�

• The protective filter protects the lens surface from damage caused by

processed chips�

• The protective filter eliminates the time and effort that is required to perform

maintenance on the lens when oil mist or dust affixes to its surface�

The blue cut filter blocks the wavelength of blue LED light� Use this filter in

combination with the wavelength conversion sheet to cut the excess blue LED

light components that shine on the workpiece�

Focal distance and lens selection

The relationship of lens focal distance, WD (working distance) and FOV (field of view) is

shown in the graph (lens selection chart) on the right� The log vs log graph shows lines

indicating the relationship between WD and FOV for different lenses with different focal

specifications (3�5 mm, 6 mm, 16 mm and 50 mm)� The WD and FOV for a lens can be

determined at the intersection of these lines� In a range where the WD is outside of the

lenses normal specification close up rings can be used to change the focal length of the

lens� Close up rings are mounted in between the lens and the camera and on the graph

areas of the lens line that have a bracket around them indicate the size of close up ring

(mm) along with the WD and FOV range they can be used for�

Close-up ring

Example: For a 45 mm FOV at a lens focal distance of 16 mm and with a CCD size of 3�6 mm, WD should be 200 mm�

WD = 16 mm x45 mm

= 200 mm3.6 mm

45 mm

16 mm

3.6 mm

WD=200 mm

Example: Using a 50 mm lens with a 50 mm close up ring you can have a 3 mm FOV at a WD of 90 mm (intersection of red lines)* Working distances and fields of view other than those shown in the

field of view graph are determined according to the proportional relationship shown within the field of view graph� Also, the resolution is reduced in the range in which close-up rings are used�

WD (working distance) and FOV (field of view) are determined by the lens focal distance and the cameras CCD size� When WD is outside the range where close up rings are required, the following proportional expression can be used for WD and FOV�

WD=

Focal distance

FOV CCD size

* There are differences between lenses, so the same field of view and the same WD may not be obtained even under the same conditions� When attaching the lens, prepare an adjustable installation jig� Also, WD in the field of view graph indicates the distance from the tip of the lens fitting to the workpiece�

Macro lens selection

ResolutionCompatible image/CCD size

The field of view that is actually imaged is determined according to the optical magnification written on the macro lens and the size of the CCD used�

For example, let us consider KEYENCE 2 megapixel and 5 megapixel cameras.

The size of the CCD can be determined by multiplying the unit cell size and the number of pixels. Using a lens with an optical magnification of x1 or x4 gives the following fields of view.

The resolving power is prescribed for each lens� Generally speaking, for cameras with high pixel counts, the unit cell size (the size of a single pixel) is small, which means that lenses with high resolution are required�

With a x1 lens, the CCD size equals the field of view�

The maximum compatible image/CCD size is written on each lens� Check that the CCD size used is less than or equal to the compatible image/CCD size� If the compatible image/CCD size is greater than the CCD size, there are no problems� If the compatible image/CCD size is less than the CCD size, vignetting, in which the periphery of the image is darkened, may occur�

With a x4 lens, the field of view is 1/4 the CCD size�

Aperture and depth of field

Lens resolution and resolving power

Relationship between depth of field and resolution

51

1) A lens with a shorter focal distance provides a larger depth of field�2) As the lens-to-target distance becomes greater, the depth of field becomes larger�

NOTE: When close-up rings and a macro lens are used, the depth of field is naturally reduced�

3) As the aperture is reduced, the depth of field becomes larger� NOTE: Even with the same lens, you can easily obtain focused images by increasing the illumination intensity with the aperture reduced�

Depth of field means the range where an image is kept in focus� As the depth of field becomes large, the lens provides higher tolerance against vertical movement and subsequently a more stable inspection�

Not only are the detailed edges displayed more clearly but there is also sufficient contrast between the white and black parts� This lens has a variable aperture, so the balance between resolution and depth of field can be adjusted by reducing the aperture (increasing the F-stop)�

The edges are not clear and, in addition, the contrast is extremely low� However, the depth of field is deeper than that obtained with the lens on the left�

Comparison with a 5 megapixel, x2 optical magnification macro lens

Test chart

The number of pairs of white and black lines that appear to be separated per millimeter in the white/black chart of the

image surface is called the resolving power� Also, the minimum pitch with which two points that are separated by a

small amount can be visually distinguished is called the resolution� Normally, the resolution is used to refer to the target

object and the resolving power is used to refer to the image�

Lens with a depth of field of 0.13 mm and an F-stop of 6.8 (CA-LMHR20)

Lens with a depth of field of 0.4 mm and an F-stop of 15.4 (CA-LM2)

To easily see and calculate depth of field a ruler can be used on an inclined surface� Taking the two extreme points on the ruler (top and bottom) when the mark is last in focus gives the hypotenuse distance of a triangle� Knowing the incline of the surface means the depth can be calculated with a simple trig calculation�

Sin θ =Depth of field

Top ruler point - Bottom ruler point

Alternatively the height difference of the two points will also result in the same value�

Aspherical lens

Floating structure

Colour aberration

Generally, spherical lenses are used in standard lens design� If a machine vision lens is comprised of spherical surfaces only, aberrations can easily occur, resulting in blurred or curved images� On the other hand, the CA-LHR Series uses “aspherical lens”, whose surfaces have been designed in a combination of various curvatures� Aspherical designs reduce lens thickness, providing compact design suitable for machine vision environments, while suppressing aberrations at the same time�

The CA-LHE/LHR/LH Series lenses are comprised of up to 11 lenses grouped at the front or back of the lens� CA-LHE/LHR/LH Series has a floating mechanism that can move the front and rear groups of the internal lenses separately, so that several lenses can work together effectively� When the front group of lenses moves during focus adjustment, the rear group of lenses moves to an appropriate position for optimised distortion correction� Thus, the CA-LHE/LHR/LH Series ensure high performance by maintaining optimum positions for the lens groups whether the target focal point is near or far to the lens and camera�

When a lens is comprised of a combination of several optical glasses, colour aberration is inevitable� Colour aberration means a focus position difference due to wavelength� The refractive index of glass or plastic varies depending on wavelength� Therefore, when light is received, the focus position varies depending on the range of light and associated wavelengths, causing the captured image to be blurred� The CA-LHE/LHR/LH Series uses “low-scattering glass” for the lens material, in order to suppress colour aberration to a minimum� Thus, the CA-LHE/LHR/LH Series obtains a low refractive index and low scattering characteristics which are not available with general optical glass, resulting in higher resolution than conventional lenses�

F-stop

The F-stop (also known as the F-number) is a reference that indicates the brightness of the lens� Accurately speaking, the F-stop is a value obtained by dividing the lens’ focal length by the diameter of its entrance pupil�The “F” of F-stop comes from the word “focal�”

In reality, a lens does not transmit all the light� The lens reflects some of the light� Moreover, using multiple lenses in order to reduce aberrations decreases the amount of light that is transmitted� With this in mind, lenses that transmit a large amount of light and result in a bright image are expressed as being “bright” and, on the other hand, lenses that transmit a small amount of light are expressed as being “dark�”The relationship between the focal distance of a lens and the diameter of its entrance pupil—that is, the F-stop—is one of the major factors that determines whether a lens is bright or dark� “Bright lenses” are those with small F-stop values, and “dark lenses” are those with large F-stop values� For general compact cameras, “F = 2�5,” “1:2�5,” or a similar indication is made on the lens to indicate that the F-stop is 2�5�

Distortion

Peripheral resolution and peripheral light intensity difference

53

Typical machine vision distortion means there is a ratio of difference between the centre and outer points of a captured image� Due to aberrations the level of distortion gets greater the further you are from the centre of the image� There are two types of distortions: “barrel” (negative ratio) and “pincushion” (positive ratio)� As the absolute value of distortion becomes smaller, so the lens provides a more consistent “flatter” image and higher precision�

The CA-LMHR Series attains distortion-free (0�02% or less) images, which makes it possible to capture images with no distortion even at the edges of the screen for applications such as dimension measurement�

Generally speaking, the smallest F-stop is obtained when the

aperture is fully open� This also gives the best resolution at the

centre of the lens�* However, the resolution on the periphery of

the lens and the difference between light intensity at the centre

of the lens and on the periphery of the lens both take on their

best values when the lens aperture is reduced to a certain

degree� The larger the CCD size, the clearer this trend

becomes�

F1.8 (fully open)

5 megapixel + CA-LHR16

F3.6

(In this situation, the light intensity is 1/4 that of the F1�8 situation� The shutter speed is adjusted so that the centre brightness is the same�)

Reducing the aperture leads to less of a decrease in peripheral light intensity and also improves the peripheral resolution� Generally speaking, the overall balance is at its best when the F-stop is 1�4 to 2 times the value obtained when the aperture is fully open�

* Depending on the lens, the highest centre resolution may also be obtained by slightly reducing the aperture�

Q & A

I saw the resolution in the lens specifications� Is it impossible to perform imaging at values lower than the resolution?

The resolution listed for macro lenses and similar lenses indicates the distance between two lines at which the lines can be recognised�It does not mean that a lens with a resolution of 10 μm cannot recognise a workpiece moving 5 μm� So long as the pixel resolution is sufficient, it is possible to recognise movement of a workpiece at or below the lens resolution�However, scratches and pin holes whose size is at or below the resolution cannot be imaged�

How is the pixel resolution determined?

The pixel resolution is determined by dividing the field of view by the number of pixels of the CCD�With the same field of view, a high-pixel camera gives a higher pixel resolution, which is useful in detections�

Why can’t I focus images to the depth of field listed in the catalogue specifications?

The depth of field listed for macro lenses and similar lenses is a value that has been calculated with a ø40 μm permissible circle of confusion� This has been the custom ever since the resolution of 240000 pixel-class cameras started being expressed as the standard� With current high-pixel cameras, images will not be brought into focus according to the values in the catalogue specifications� There is a noticeable divergence between the catalogue values and the actual values the lower the macro lens magnification becomes (the wider the field of view displayed by the lens becomes)� However, the degree to which unfocused images can be permitted depends on the application, so the focus must be checked with the actual workpieces�Also, our lineup includes macro lenses that are equipped with apertures� Reducing the aperture deepens the depth of field, so it is possible to adjust the depth of field while maintaining the CCD�

* Reducing the aperture deepens the depth of field but also makes the resolution worse�

With the aperture fully open, a high resolution is obtained at the centre of the image, but the edges of the screen become dark due to the peripheral light intensity difference, which causes the resolution in this area to become low�
