TRICOR’s Model 600 ImagingSpectrophotometer is an exciting newproduct for measuring color. Unlikeother imaging colorimeters, the Model600 can be used to measure radiatedsources, reflectance as well astransmittance from 380nm to 780nm.This spectral information can be usedto calculate various color coordinates;by convolving the spectral curve witha user specified type of illuminationand standard observer. The softwareallows for any combination ofilluminant (11+ types) and standardobserver (CIE 1931 or 1964).Resulting color units include XYZ(Tristimulus Values), xyz (chromaticitycoordinates), L*a*b* (CIELAB 1976),Lab (Hunter Lab 1946), u’v’ (CIE1976 UCS), L*u*v* (CIE 1976CIELUV) and CCT (Correlated ColorTemperature).

Many other color systems on themarket use the tristimulus method ofmeasuring color. The tristimulusmethod has a major distinctdisadvantage compared to thespectrophotometric method. Thelimited tristimulus method simplymeasures a red, green and bluereflectance over an area with a singleilluminant. These devices give noinformation regarding spectral/reference content; and therefore lackthe capability to directly detectmetamerism.

Model 600 Capability Description: Virtual Spot Spectrophotometer (VSS)

Introduction

The Model 600 (non-contact) Imaging Spectrophotometer is an instrument that measures color on surfaces at a high resolution. The pixel scale can be increased for any specific application. “Typical” pixel size is about .008” resulting in an overall field of view of 8.5” x 11” (A-size). Keep in mind that the user can use “as much” or “as little” of the 1.2 million independent spectral curves as needed for any given application, or they can combine the pixel data in a fashion that simulates a specific size aperture appropriate for their particular application. This flexibility gives the Model 600 the ability to measure a wide range of complex color schemes, textures and applications that were not previously possible with “spot” instruments. It also gives the instrument the capability to: 1) “simulate” the scrutiny level of the human eye, 2) extract complex information for manufacturing and R&D purposes, and 3) measure color over large extended areas. What is a Virtual Spot Spectrophotometer (VSS)?

A conventional spot spectrophotometer “spectrally averages” everything it sees in its measurement aperture. For example, if you have a 2mm measurement aperture device, it will measure a single “average” color of everything contained within a 2mm diameter area. A virtual spot spectrophotometer (VSS) performs the exact same function; however, it does it virtually. In this context, “virtually” is referring to the fact that it is done within the computer. This gives the user full flexibility in defining the size of the aperture and placement anywhere within the system’s field of view. It also allows the user to perform 100’s or 1000’s (or even millions!) of measurements within an image in seconds. Scrutiny Level of the Human Eye

At this point, I would like to talk about the resolution limitations of the human eye and how it varies. Based on widely available human eye resolution data, it was derived that the visual acuity of the human eye at 12 inch distance with a high contrast target is approximately .007 inches. Simply stated, the “average un-aided human eye” cannot discern anything smaller than the acuity limit. In other words, if multiple colors exist in an area that is smaller than the acuity limit size at a given distance, the human eye will


average those colors together into a single color. Acuity size varies with distance and “typical” values are shown in the following table. Theoretically Distance (feet) Acuity Size (inches) Acuity Size (mm) Imperceivable DPI 0.5 .003 0.089 600 1.0 .007 0.178 300 2.0 .014 0.356 140 3.0 .021 0.533 95 4.0 .028 0.711 72 5.0 .035 0.889 57 5.6 .040 1.008 50 11.3 .079 2.000 25 16.8 .118 3.000 17 22.5 .157 4.000 13 28.1 .197 5.000 10 Application

At the time of this writing, the VSS is implemented in the application software, ISPControl in two ways. The simplest implementation is the ability to manually draw and/or place a specific size rectangular aperture over the image in order to extract a single convolved (or averaged) color. This would be equivalent to placing a spot spectrophotometer (with that same measurement aperture size) over that same area and making a non-contact measurement. A more encompassing implementation includes the ability to perform a Full Frame Delta-E analysis using a user-defined aperture size. The Delta-E map allows the user to “see” the entire surface and how it compares to a master in its entirety. This is accomplished because of the software’s ability to utilize this VSS capability which is inherent only to this device Conclusion

Various industries use different size measurement apertures. Some “typical” industries along with the associated “commercially available” aperture sizes are listed below.

1. Textiles 3 – 30mm apertures depending on the specific textile 2. Printing 1.5 – 6mm depending on the print quality (dpi) 3. Food 1 – 2.5in depending on the product 4. Flooring 6 – 30mm apertures depending on the product 5. Paint 3 – 12mm 6. Plastics 3 – 12mm


The VSS capability gives the Model 600 versatility to be used in any color measurement application. That application can include the measurement of color over very small areas and can also be used to measure color over large extended areas. The Model 600 in its “standard configuration” can apply a VSS with an aperture size ranging from 0.2mm to 200+mm. Larger and smaller apertures are easily achievable by changing measurement distance. This is all possible because of the VSS. A word of warning should be given when specifying color tolerances and aperture size. One should consider visual acuity when specifying aperture size for a given product or application. Specifying (or using) measurement aperture sizes smaller than visual acuity should be avoided, unless details beyond that limit are important to the manufacturing process. The simple fact that the Model 600 provides the capability to measure extremely small areas should not be used as the criterion for aperture size specifications. Note: As capabilities of the Model 600 Imaging Spectrophotometer increase, there may be even more implementations of the VSS capability. Contact TRICOR Systems Inc for the latest information regarding capabilities for your specific application requirements.

TRICOR’s DOI/Haze Meter is ideally suited for measuring flat, non-textured high reflectance surfaces. The Model 807A design is in accordance with ASTM E430 (method C) and D5767 (method A) and is used to measure ±3 degrees around the specular lobe centered at 30 degrees in approximately 220 increments. That’s an angular sample size of 1 sample per 1.6 minutes of arc! This allows differentiation between samples with very small differences in reflectance characteristics.

Operators need only press 1 button on the unit to obtain a measurement in less than 4 seconds. Computed results include Rs (specular gloss), DOI (Distinctness-of-image gloss) and haze (2 & 15 degrees). The device can help quantify reflectance, DOI, haze, sheen, reflection directionality, reflectance haze, metallic brightness for metals, glass, ceramics, painted surfaces and any other high reflectance surface. The system was designed as a direct replacement of the obsolete Dorigon II.

The system is operated via RS232 from a PC. Quickly switch from a mirror standard to a black glass standard for non-metallic measurements. Statistical sample averaging is performed. Each measurement is time and date stamped. Data can quickly be downloaded directly into a MS Excel spreadsheet.

Low power consumption and power saving features allows standard AA NiCd type batteries to be used. Battery life is in excess of 10 hours of continuous operation without need for new batteries. An optional ac adapter and battery charger is available for use with rechargeable batteries. A Non-contact optional configuration is also available.

The Model 807A can be configured for either contact or non contact measurements. The non contact configuration may allow integration into a production line.

Applications include:

• Metal

• Painted products

• High polished/glossy surfaces

• Tiles

• Pottery

• Chrome Finishes

• Countertops

• Flooring

• Glossy Paper

● Can be customized to measure your product’s appearance characteristics

The Model 820 Video Photometer measures the absolute brightness of any size sample or scene and pro-vides quantitative data in fL or cd/m2. The 820 is used to measure the performance of lamps, LEDs, backlit panels, control switches, etc. It also quantifies paint reflectance, hemi-spherical reflectance, micropitting, mirror reflective haze, contrast, and other appearance characteristics. The 820 generates a 640 x 480-pixel image with a digitized 256 gray scale. It uses TRICOR’s Eyeppearance™ software, a Windows® compatible PC-based software system, to provide analysis tools used to establish photometric levels for an image.A user-friendly Windows® interface offers many menu options for analyzing the acquired gray scale image; however, the real potential of Eyeppearance™ is realized when a calibration transform file is loaded for the image. The calibration transform translates the relative gray levels into absolute radiometric levels. Pixel radiance levels and histogram distributions are given in photopic units. Menu options, such as the Enhance option, provide a close coupling of the image data and the histogram distribution. The image is highlighted in green for a given section of the histogram. The user can use the mouse to quickly change the highlighted radiance levels in bandwidth and position on the histogram distribution. Also, false coloring can be applied to the image allowing the user to readily see those areas below, above, and within the user-specified tolerance band. Quantitative values associated with the highlighted area(s) are then displayed on the PC screen. Another powerful feature of Eyeppearance™ is its ability to define up to 256 regions of interest. Each region of interest may be any region as outlined by the user using the mouse. From this region an active subset can be selected, which establishes a new histogram distribution and limits image analysis to this active region only.

The Model 823 Video Photometer measures the absolute brightness of any size sample or scene and pro-vides quantitative data in fL or cd/m2. The 823 employs a progressive scan non-interlaced IEEE 1394 “Firewire” camera to measure the performance of lamps, LEDs, backlit panels, control switches, etc. It also quantifies paint reflectance, hemi-spherical reflectance, micropitting, mirror reflective haze, contrast, and other appearance characteristics. The 823 generates a 1024 x 768-pixel image with a digitized 8 or 10 bit gray scale. It uses TRICOR’s Eyeppearance+™ software, a Windows® compatible PC-based software system, to provide analysis tools used to establish photometric levels for an image. A user-friendly Windows® interface offers many menu options for analyzing the acquired gray scale image; however, the real potential of Eyeppearance+™ is realized when a calibration transform file is loaded for the image. The calibration transform translates the relative gray levels into absolute radiometric levels. Pixel radiance levels and histogram distributions are given in photopic units.
