CAPABILITIES
Optical Engineering, Precision Fabrication, Assembly, and Measurement
Mosaic Optoelectronics approaches specialized optical components as a connected process: understand the imaging or optical requirement, develop a practical configuration, manufacture and assemble the component, and verify the characteristics that matter to its function.
A CONNECTED PROCESS
Define, Build, Assemble, and Verify
Optical performance is closely tied to material selection, crystal orientation, geometry, fabrication, element sequence, assembly, and measurement. Treating these activities together helps reduce the gap between an optical concept and a practical manufactured component.
01 · DEFINE
Understand the Optical Requirement
Begin with the imaging problem, optical function, sensor, wavelength, polarization, geometry, and mechanical constraints.
02 · FABRICATE
Produce the Optical Elements
Material preparation, geometry, thickness, surface preparation, polishing, and handling are developed around the needs of the optic.
03 · ASSEMBLE
Control Element Order and Orientation
Multi-element optics require the correct sequence, rotation, orientation, cleanliness, spacing, and mechanical integration.
04 · VERIFY
Measure the Result
Dimensional and optical measurements provide process feedback and help confirm characteristics important to the finished component.
OPTICAL ENGINEERING
Start With the Complete Imaging System
Custom optical work is most useful when the component is developed around the actual imaging problem rather than treated as an isolated piece of hardware.
For imaging applications, relevant information can include sensor pixel pitch, lens performance, magnification, wavelength, polarization, beam geometry, available optical spacing, image artifacts, and the mechanical envelope.
For optical anti-aliasing in particular, sensor sampling cannot be considered independently from the image delivered by the lens. Available lens MTF data, object detail, magnification, and representative images can therefore be valuable engineering inputs.
From those requirements, material, geometry, element orientation, stack sequence, optical behavior, and a practical manufacturing approach can be evaluated together.
ENGINEERING INPUTS
- Required optical or imaging function
- Sensor model, format, and pixel pitch
- Representative images or artifacts
- Lens and available MTF information
- Magnification and working distance
- Operating wavelength or spectral range
- Polarization requirements
- Optical-path and aperture constraints
- Component dimensions and mechanical envelope
- Existing drawings or sample components
PRE-SENSOR OPTICAL CONDITIONING
Engineering the Light Before It Reaches the Sampling Grid
Some imaging problems are most effectively addressed in the optical path, before image information is converted into discrete sensor samples.
Birefringent elements can produce controlled spatial displacement of image-forming light. Multiple elements can be combined to create selected point-spread patterns and spatial-frequency behavior.
Polarization-control elements can also be incorporated where the optical architecture requires management of the emerging polarization state.
The resulting component may therefore combine spatial conditioning, birefringence, polarization management, and mechanical integration within one multi-element optical stack.
MATERIAL AND GEOMETRY
Optical Function and Manufacturability Must Agree
A theoretically useful optical material or geometry is only valuable if it can also be fabricated, handled, measured, assembled, and integrated reliably.
Material Selection
Optical properties, birefringence, wavelength behavior, mechanical characteristics, and processing requirements can influence the choice of crystal or optical material.
Geometry and Orientation
Thickness, aperture, external dimensions, crystal-axis orientation, element rotation, and optical-path constraints can define both the optical behavior and manufacturability of the component.
Design for Manufacture
Optical requirements are considered alongside practical fabrication, measurement, handling, assembly, and integration requirements.
PRECISION OPTICAL FABRICATION
Turning Specialized Materials Into Functional Optics
Optical fabrication requires control of geometry and surface condition while accounting for the behavior of the material being processed.
Birefringent materials such as quartz and lithium niobate introduce additional considerations involving crystal orientation, handling, edge condition, surface preparation, thickness, wedge, and element geometry.
The manufacturing sequence depends on the material, component geometry, optical requirements, tolerances, and quantity.
FABRICATION CONSIDERATIONS
- Material preparation
- Cutting and shaping
- Thickness control
- Wedge and parallelism
- Surface preparation
- Optical polishing
- Edge condition and handling
- Crystal orientation
MANUFACTURING PROCESS
Progressively Refine the Component
Precision optical manufacturing develops a component in stages, with inspection and measurement used between steps to guide the process toward the required geometry and surface condition.
01
Prepare
Confirm material, crystal orientation, starting geometry, and manufacturing approach.
02
Shape
Develop component dimensions and geometry while maintaining suitable process allowance for later finishing.
03
Finish
Refine optical surfaces, thickness, and geometry toward the required surface and dimensional result.
04
Verify
Measure relevant dimensional and optical characteristics before the component proceeds to assembly or final inspection.
MULTI-ELEMENT OPTICAL ASSEMBLY
Element Orientation Can Be Part of the Optical Function
In birefringent optical stacks, assembly is not simply a mechanical operation. The relative orientation of each optical element can directly determine the behavior of the finished component.
Element order, crystal orientation, rotational alignment, cleanliness, seating, spacing, and polarization-control elements may all need to be managed during assembly.
This is especially important for multi-element anti-aliasing filters, retardation assemblies, and custom crystal-optic stacks.

OPTICAL METROLOGY
Measurement as Part of Manufacturing
Measurement provides feedback during fabrication and helps determine whether the manufacturing process is moving toward the required result.
Depending on the optic, relevant measurements can include dimensions, thickness, wedge, surface condition, optical flatness, transmitted wavefront behavior, orientation, or other application-specific characteristics.
Interferometric methods can be used where appropriate to evaluate optical surfaces or wavefront behavior with high sensitivity.

MEASUREMENT AREAS
Verify What Matters to the Optical Function
Not every component requires the same inspection method. Measurement should be selected according to the characteristics that actually influence optical performance and system integration.
Dimensions
External geometry, thickness, aperture, and other physical characteristics can be checked during fabrication.
Surface Condition
Optical surfaces can be inspected for condition and manufacturing defects appropriate to the application.
Optical Geometry
Flatness, wedge, parallelism, orientation, or wavefront-related characteristics may be evaluated according to component requirements.
Assembly Verification
Multi-element assemblies can be checked for element order, orientation, seating, geometry, cleanliness, and other relevant characteristics.
DEVELOPMENT AND PRODUCTION
Prototype Work Can Inform the Manufacturing Process
Custom optical components often benefit from an initial development phase where optical behavior, geometry, fabrication methods, assembly, and measurement approaches can be evaluated before repeat production.
Evaluate
Review the optical requirement, available design information, material, geometry, and anticipated manufacturing challenges.
Prototype
Produce components or assemblies that allow the optical approach and manufacturing process to be evaluated.
Refine
Use fabrication, assembly, and measurement results to improve the process for subsequent components or repeat production.
