Buying Dielectric Coatings

Dielectric coatings, also known as thin-film coatings or interference coatings, consist of thin (typically sub-micron) layers of transparent dielectric materials deposited on a substrate. They are used for anti-reflection coatings, dielectric mirrors, polarizers, and various other purposes. Fabrication methods include electron beam evaporation, ion-assisted deposition, and plasma reactive sputtering.
