A thin-film coating filter, or interference filter is a sophisticated coating used to selectively pass light of a small range of wavelengths while reflecting others. With over 90 years of thin-film design experience on staff, chances are good we can design whatever coating you’ll need to satisfy even the most demanding applications. Here are some of our most popular thin-film designs. If you do not see a graph you’re interested in, please contact us at 866-216-6225 ext 108, to discuss your program in more detail.
