Optical coating

Material which alters light reflection or transmission on optics

An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflection coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and camera lenses.
