Product description
Vertical integration enables us to supply the entire ring laser gyroscope components package: RLG frame and optical components.
Our integration of capabilities delivers superior performance and streamlines sourcing.
We design and manufacture our ring laser gyroscope components in Moorpark, California, United States.
There are many RLG components within the RLG – each performs unique functions and is optimized accordingly.
Zerodur® frame
The Zerodur® frame must deliver maximal stability over a large range of operating environments (namely, temperature, humidity, and environmental composition). We have 40 years of experience producing high-quality, consistent, Zerodur® frames.
Precision mirrors and optics
Flat, wedged, and curved mirrors used in RLGs are superpolished with surface roughness better than 1 Å RMS with high-reflectivity low-loss IBS coatings designed to survive extreme environmental conditions.
Precision beam splitters, prisms, and wedges complete the assembly.
Metrology
Extensive metrology capabilities are critical in order to meet and exceed difficult specifications for ring laser gyroscope components. We utilize the following state-of-the-art measurement systems:
- 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 λ/50
Our facilities are certified to ISO9001 and AS9100D: 2009 Rev.C. G&H businesses comply with ITAR legislation and are registered with the US government.
Coatings
From high transmission broadband anti-reflection coatings to V-coats for high energy applications, our extensive coating capabilities for precision optical components deliver performance across the spectrum from the UV to the FIR.
Environmental Testing
Environmental testing of components and coatings is critical for the assurance of performance in rugged conditions. G&H environmental testing capabilities include MIL-C-675C, MIL-C-48497A, MIL-E-12397, and MIL-M-13508C for endurance against abrasion, adhesion, humidity, temperature, and environmental conditions.
