Chroma Technology Corporation

Chroma Technology Corp. is a manufacturer of interference filters for the ultra-violet, visible and near-infrared portions of the spectrum, including band pass, multiple band pass, and long and short pass filters, as well as beamsplitters, dichroic mirrors and laser rejection filters. We specialize in precision spectral control, including extra high signal-to-noise ratio filters and those with rapid cut-on and cut-off profiles. The manufacturing process involves precisely depositing, in a vacuum, extremely thin layers of two or more materials on a glass or similarly transparent substrate. Chroma was organized by several talented individuals who wanted to create a working environment entirely different from the typical corporate structure. 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. As an employee owned company, Chroma has grown from seven employees with sales of $314,200 in its first year of business, to over 100 employees today. Chroma's filters are distributed worldwide, though all manufacturing occurs in the United States.
