We are a leading designer and manufacturer of precision optical components and fiber-optic couplers for inertial navigation systems used in avionics and defense. Whether the application calls for a ring laser gyroscope (RLG) for airborne or maritime navigation or a fiber-optic gyroscope (FOG) to guide the flight of a missile or UAV, we offer proven expertise in the development of both legacy and emerging inertial platforms.

Our heritage in precision optics, materials and optical applications, as well as our integration capabilities, enables us to deliver products with superior performance and streamlined sourcing.

RLGs

We develop and deliver complete RLG optical assemblies as well as subassemblies that are built to fit your system. Our vertical integration enables us to supply the entire RLG package, including the frame and its optical components, as well as dedicated metrology to ensure reliable and consistent operation.

FOGs

Our dedication to fiber optic innovation over the years is observable in the quality and effectiveness of our fiber optic components. All of our components are designed for harsh environments and undergo rigorous qualification processes and optical testing to ensure high reliability operation.

RLGs

Zerodur® frames

With over 40 years of experience of producing high-quality and consistent Zerodur® frames, our RLGs deliver maximal stability over a large range of operating environments (namely, temperature, humidity, and environmental composition).

Optical components

Flat, wedged, and curved mirrors used in RLGs are superpolished with surface roughness better than 1 Å RMS, with high-reflectivity IBS coatings designed to survive extreme environmental conditions. Alongside our mirrors, we manufacture precision beamsplitters and combiners, prisms, and wedges using our advanced facilities and expert engineers to complete the assembly.

Metrology

Extensive metrology capabilities are critical to our ability to meet and exceed difficult specifications:

• Zygo® ZeMapper™ for surface roughness and structure <1 Å
• OGP® CMM for geometrical tolerances down to sub-micron features
• 18” Zygo® Interferometer measures flatness up to 1/50th wave

FOGs

Laser sources

Our line of high power diodes feature ruggedized, epoxy-free designs that are built to operate for long periods of time over wide temperature ranges and high shock/vibration environments. With an emphasis on stability and low noise, our sources are ideal for FOGs.

Passive components

Manufacturing of high reliability fused fiber optic components, such as splitters and couplers, is carried out on specially developed workstations. Advanced fiber management, in-process screening, and customer specific validation tests are implemented to further enhance component reliability. The ultra-low loss of our fused fiber components promotes low noise and high performing FOGs.

Optical subassemblies and multichannel integration

With our extensive experience with all of the components in a FOG, we are also able to offer the development and manufacture of optical subassemblies for FOGs, including multichannel integration. Contact us today to discuss your requirements.
