Chroma Technology

Chroma Technology Corp. is a manufacturer of interference filters for the ultra-violet, visible and near-infrared portions of the spectrum, including bandpass, multiple bandpass, and long and short pass filters, as well as beamsplitters, dichroic mirrors and laser rejection filters. The manufacturing process involves precisely depositing, in a vacuum, extremely thin layers of two or more materials on a glass or similarly transparent substrate. Founded in Brattleboro, Vermont, in May 1991, Chroma quickly established itself as a leader in filter designs. From its inception, Chroma has worked closely with the community of molecular and cell biologists worldwide to develop the best possible solutions to applications requiring fluorescence filters.
