Optometrics Patents Diffraction Grating for Holographic Weapon Sight

Optometrics Develops Hybrid Grating and Optical Filter for EOTech Holographic Weapon Sight

A search for diffraction grating led EOTech, a U.S. weapons accessory manufacturer to contact Optometrics. EOTech expressed interest in redesigning the diffraction grating, a key component in their holographic weapon sight. The diffraction grating they were using had proven to be less than reliable, and there was an urgent need regarding replacing the existing component with a more favorable part in quality, durability and price.

EO-Tech-hybrid-diffraction-grating-gun-sightOptometrics’ engineering team designed and patented a hybrid diffraction grating and optical filter which solved the technical issues for EOTech. The solution exceeded EOTech’s expectations on environmental durability, spectral precision and optical quality, and simplified the manufacturing process. Optometrics’ success at manufacturing this key component led to EOTech requesting additional components and complete assembly for their holographic weapon sight.
