Chroma is a leading manufacturer of highly precise optical filters using thin-film coating technology. Our reputation is built on dedicated customer service, including technical and application support. We manufacture high-performance optical filters covering a spectral range from 200-5000nm with superior durability and longevity, across many industries and applications. Our filter types include long, short, and multi-bandpass filters, notch rejection filters, neutral density filters, beamsplitters, and reflective metal mirrors. Our high-performance filters offer the highest levels of transmission and blocking of unwanted wavelengths, resulting in high signal/noise ratios. Sputtered hard coatings provide superior durability, including resistance from damage resulting from harsh environmental conditions such as heat and high humidity, as well as from scratches and handling.  We’re so confident that these filters will last as long as you need them to that we offer an industry-leading lifetime warranty. 

Offering off-the-shelf, custom, and high-volume production products and solutions, we can design and deliver optical filters that do precisely what our customers need. All manufacturing occurs in the United States with worldwide distribution and sales support.
