Precision Optics
G&H manufactures precision optical components and assemblies for applications in research, industry and defense. Our products for laser cavity and beam conditioning include active and passive components as well as nonlinear crystals. Our custom lenses and housed subassemblies find application in transmission and imaging. Much of our business involves creating high quality, custom optics for volume OEM applications and unique optics for research. Our ring laser gyro mirrors are used by every commercial airline in the world. We have provided 0.5x0.5 m KDP waveplates into national ignition facilities. From components to modules, the deep vertical integration of our supply chain allows us to maintain control over design, materials and processes, while ensuring quality and security of supply.- compliance with international export regulations

Transmission & Imaging
Transmission and imaging is a broad field involving the use of precision optical components, mounted optics, sub-assemblies and integrated modules. It may involve UV, visible, SWIR (short-wave infrared), MWIR (mid-wave infrared), or LWIR (long-wave infrared) light.

- Spherical, aspheric, and single point diamond turned lenses
- Magneto-rheological finishing (MRF®) linked to sub-aperture stitching (SSI) interferometery
- Optical coatings from deep UV, through visible and IR, to LWIR
- Doublets, triplets, housed subassemblies
- Advanced optical metrology
Research Grade Mirrors & Substrates
We have developed superpolishing capabilities when combined with robust Ion Beam Sputtered (IBS) coatings create high surface figure and surface quality mirrors:- Laser cavity and beam routing mirrors – high LDT coatings, enhanced metal coatings
- Synchrotron mirrors – low scatter, high surface figure, high surface quality
- Silicon carbide (SiC) mirrors – low mass, thermally stable mirrors for aerospace applications
- Ring laser gyro mirrors (RLGs), frames, and diaphragms – for navigation and guidance systems in aerospace and defense
