Filter Coatings

July 10, 2019

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.

Anti-Reflective Coatings

July 10, 2019

An anti-reflective (AR) coating is a type of optical coating applied to the surface of an optical element to reduce surface reflection. In typical optical systems, this improves the efficiency since less light transmission is lost due to reflection. In complex systems the reduction in reflectance also improves the contrast of the image by elimination of stray light. The primary benefit of an AR coating is the elimination of the reflection itself, while promoting the transmission of light waves at intended wavelength ranges. With over 90 years of thin-film design experience on staff, chances are good we can design whatever…
