Spectrogon US, Inc.

Spectrogon's thin film optical products function from the wavelength regions of 200 nm in the ultraviolet to 20 000 nm in the infrared. The holographic diffraction gratings function from the very short wavelengths in the UV region to approximately 3 000 nm in the infrared.

The thin film optical product line includes: various types of interference filters - narrow bandpass, broad bandpass, long-wave and short-wave pass and neutral density. Other optical products are: beamsplitters, anti-reflective coatings, mirror coatings and specialised thin film coatings. The holographic grating product line includes: plane and concave, replicated and blazed.
