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

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.
