Understanding Optical Coatings

February 20, 2019

Optical coatings and the coating process itself are often the last thing engineers consider when designing both simple and complex optical systems for prototype and wide-scale manufacturing. Our hope with this paper is to help and educate our future customers on the multiple types of optical coatings and some of their unique proprieties. Anti-reflection Anti-reflection films are used to maximize light transmission while increasing contrast and eliminating ghost images. Typically, these coatings are quite robust when tested for abrasion and environmental resistance. Most transmissive optics have some type of anti-reflection thin film on at least a single surface, but in…
