Optical Coating


Vacuum coating on optical components has a long history. Optical components need to be coated with one or more layers of optical films on the surface to enhance their optical effect for anti-reflective films, high-reflective films, polarizers, beam splitters and filters Film... etc. Optical films are generally on glass or plastic substrates made of dielectric or metal materials to form a single-layer or multi-layer film, which uses the interference of light to change the transmission or reflection characteristics of light.

DAHYOUNG Vacuum has focused on vacuum coating for decades, providing coating solutions for customers in a variety of industries. Close industrial university relationships and exchanging of knowledge and technology is used for foundry requirements in the optical coating process demands for anti-reflective films, high-reflective films, polarizers, beam splitter and filters.
