Get Exactly the Imaging Performance you NeedMicroscope objectives are a critical

component in high-performance

optical systems as they determine

the image information content

that can be acquired, hence the

sensitivity, accuracy and throughput

of the instrument. However, most

commercial objectives available and

in use today were not designed for a

specific application. They are generally

optimized for best performance at

the center of the field of view (FOV),

and color correction is either limited

or enhanced over a broad wavelength

range in the most expensive

objectives. And they generally exhibit

high variability and thermal sensitivity,

falling to meet today’s demanding

instrument repeatability requirements.

Another limitation is the difficulty to

precisely quantify or model the

actual performance of available

off-the-shelf objectives.

Gain a competitive edge with our custom objectives

Stop compromising! Melles Griot is

happy to work with you to provide a

cost-competitive custom microscope

objective solution that is ideally suited

to your specific application.

By specifically addressing each of your

requirements, our custom objective

designs create differentiation that

ultimately reduces your overall

system complexity while significantly

improving performance compared to

off-the-shelf objective solutions.

High-NA, wide-FOV, diffraction-limited resolution performance

Outstanding wavefront, color and distortion correction over the entire FOV

Customization for your optical and physical requirements, including telecentricity, laser damage threshold and thermal sensitivity

Superior repeatability and guaranteed performance from prototype through high-volume production

Full flexibility and control over your overall system design

Both the positioning accuracy and the volume requirements need to be taken into account to deliver an opto-mechanical solution fully optimized for performance, manufacturability and cost.

Lens Assembly Techniques and PerformanceAt Melles Griot we know that each optical system is unique, and we employ

different assembly techniques and mounting strategies for each one, from simple

drop-in lens assemblies, to complex integrated optomechanical systems with

critical alignment and mechanical stability requirements. We have developed

a proprietary suite of lens assembly techniques to balance and match the

performance and budgetary requirements of our customers.

Conventional drop-in and cell mounted techniques provide a cost effective solution for lower precision/performance multielement lenses

Melles Griot Proprietary Exact Placement technology enables micron level mounting accuracy for the highest performing systems

Alignment turning provides a solution that balances performance close to the performance of Exact Placement technology at a fraction of the price

Each lens assembly is delivered with actual performance and characterization data at functional wavelengths

We use state-of-the-art manufacturing techniques and processes, along with the

most advanced measuring metrology tools and vertically integrated production

capabilities. The result is a robust and reliable product, with superior and consistent

system-level performance from prototypes to high volume production.

By working closely with our customers, we have routinely taken challenging

projects successfully, meeting aggressive timelines and cost constraints, and

Light Source Solutions

Put Light Where You Want it − How You Want it

Compact and Efficient Diode Laser Modules

Diode laser modules provide extremely compact and reliable sources of laser

light with minimal heat generation and maximum resistance to mechanical shock

and vibration. Most operate in a single transverse mode and provide linearly

polarized output.

Our standard Diode Laser Systems

provide excellent output power

and pointing stability from an ultra-

compact laser head. This is achieved

through state-of-the art thermal

management, which improves

performance and reliability in

harsh environments.

Custom Diode Laser Systems for

OEM applications can be configured

for direct analog and/or digital

modulation, eliminating the cost,

complexity, and alignment challenges

associated with external modulators.

We also specialize in custom-tailored

beam profiles that deliver the

precise spot you need at the point of

work, dramatically reducing system

complexity and cost—and significantly

improving system performance.

We offer a wide variety of

diode, DPSS, and gas lasers

to meet your application

needs from Next Generation

Sequencing, Cytometry,

Spectroscopy, Microscopy,

Fluorescence, Holography,

Interferometry, to Displays.

Stable, Reliable Solid-state Laser Sources

We first began manufacturing DPSS lasers for over 20 years. These devices

provide compact and reliable sources of laser light with minimal heat generation

and maximum resistance to mechanical shock and vibration.

Standard DPSS Laser Systems from

Melles Griot provide excellent output

power and pointing stability from a

compact laser head. This is achieved

through state-of-the art thermal

management and current control,

which improves performance and

reliability in harsh environments.

Fiber Optic Beam Delivery is available

for most products, in addition to

free-space beam delivery. With single-

mode fiber core sizes of approximately

4 microns, maintaining alignment,

and the resulting power efficiency

and stability can be challenging. We

address this by incorporating the

fiber launch components inside the

laser head, and maintaining them at

the same temperature as the laser

itself. The result is stable power and

efficient coupling – over time, over

temperature, and during mechanical

shock and vibration.

Field-proven Beam-combining SolutionsIf your application requires the integration of multiple light sources, we offer

a field-proven experience base to help you. Figure 1 represents a conventional

beam-combining approach.

Lasers are mounted in conjunction with beam-conditioning optics to deliver the

required spot size at the working location. This may include optical isolators,

modulation components, spectral filters and / or polarization rotators. Optics and

mounts for beam-steering and beam combining are required, both of which must

be precisely located and maintained over time and temperature to deliver stable

performance. The high component count adds cost by way of a higher purchased-

part count, supply chain complexities, inventory carrying cost, quality control costs,

assembly time, tolerance stack-up, and optical efficiency. The completed assembly

must maintain its alignment over time and temperature – wherever and whenever

your customer chooses to operate it.

Figure 2 represents a laser cartridge-based approach. This is particularly effective if

you have an application where you need to add or change laser wavelengths to an

existing system in the field.

By purchasing an integrated system, consisting of a laser, beam conditioning

optics, polarization and spectral control, modulation components (if required)

and beam-steering into a precision-aligned cartridge, your components count is

dramatically reduced. The time you spend procuring, inspecting, assembling,

and testing drops considerably, and field serviceability improves exponentially.

The end result is a plug-and-play cartridge that delivers the wavelength and power

you want, at a defined point in space, reliably and precisely over time, temperature

and shipping and handling.

Figure 3 represents the ultimate in integrated light engines. A significant

departure from “bolt-together” light engines, this is a completely monolithic,

hands-free approach.

The hermetically sealed design, combined with our patented beam-combiner

and ground-breaking mechanical design results in rock-solid stability when

subjected to mechanical shock, vibration, and temperature changes. All laser,

polarization control, spectral control, and beam steering components are held

at the same temperature in an ultra-compact package, which delivers pointing

stability better than 5 µrad per ºC, ultra-low optical noise and outstanding power

stability. Customized beam profiles, focal distances and modulation parameters are

available per your OEM requirements.

Light Source Solutions

When you need a complete optical system at the core of your life science or other high-performance instrument, our expertise in all aspects of optics combined with our proven design-through-manufacturing approach is your solution

WE ARE COMMITTED TO YOUR PRODUCT & BUSINESS SUCCESS

Systems engineering always requires tradeoffs to be made

and these decisions have significant consequences in terms

of performance, price, and reliability. This maxim is just

as true for an optical system – where illumination optics,

imaging optics, spectral optics, an autofocus system, a

detection system, and all other supporting optical, opto-

mechanical, and electronic components required to

interface the system to the overall instrument must work

flawlessly together time after time. Don’t risk bolting

together parts that weren’t designed with one another in

mind. Let us design and build a fully integrated system for

your instrument.
