Surface coatings used to control optical, mechanical and electrical properties are deposited as nano- and micrometer thicknesses of special materials. Optical coatings are deposited as thin-film multilayers of a variety of materials using specific deposition techniques. Coatings are applied to optical components that are intended for use at wavelength regions between UV and far-IR. The materials and processes used to make these coatings are described here and in the attendant materials data tables.
