About Chroma Technology
Chroma Technology Corp., founded in 1991 and 100% employee-owned, is a manufacturer of ultra-precise optical filters based on thin-film coating technology. The portfolio includes long-pass, short-pass and multibandpass filters, notch rejection filters, neutral density filters, beamsplitters and reflective metal mirrors covering a spectral range of 200–3000 nm; alternatively, a range up to 5000 nm is also stated. Products are manufactured on glass substrates using high-vacuum thin-film coating and sputtered hard coatings, which offer high resistance to heat, moisture and mechanical stress. Chroma supplies catalog products, custom solutions including design and engineering, and high-volume production; via a rapid prototyping service, custom products can be delivered in as little as about two weeks. Customer industries include Life Science & Diagnostics, Biophotonics, Astronomy, industrial automation and Machine Vision, and analytical spectroscopy such as Raman and fluorescence. All manufacturing takes place in Bellows Falls, Vermont (USA), with worldwide distribution and branches in Germany, Japan and China.

Materials & Processes
Thin-Film Coating
Precision process for manufacturing optical interference filters on glass substrates in high vacuum.
Sputtered Hard Coatings
Sputtered hard coatings with high resistance to heat, high humidity, scratches and handling.
Glass
Substrate material for all optical filters; every filter begins as a piece of glass in the vacuum chamber.
