Optical Filters, Thin Film Coatings, Holographic Gratings
Spectrogon specializes in the design and manufacture of optical interference filters, thin film coatings and components for analytical, medical, and scientific applications. Spectrogon manufactures optical filters for wavelengths from 220 to 15000 nm. The high transmission, high rejection outside the passband, fine surface quality and the coating uniformity gives our filters excellent performance. Spectrogon is the world leader in the design and manufacture of Holographic diffraction gratings for laser compression/stretching applications, tuning, and spectroscopic instruments. Spectrogon offers a huge inventory of stock filters (www.spectrogon.com) listed on our website that provides spectral characteristics for each batch, availability and prices.
