Thin-Film Coatings

Thin-film coatings are layers of material applied to the surface of an object or substrate, typically to modify its optical, electrical, or mechanical properties. These coatings are composed of thin layers of materials, often just a few nanometers to micrometers thick, deposited onto a substrate using various techniques such as physical vapor deposition, chemical vapor deposition, sputtering, or thermal evaporation.

Glossary

antireflection coating An antireflection coating (AR coating) is a thin film or coating applied to optical surfaces, such as lenses or windows, to minimize unwanted reflections and increase the transmission of light through the surface. These coatings are designed to...
dielectric coating A high-reflectance coating consisting of alternating layers of quarter-wave film of a higher refractive index and lower refractive index than the substrate. Such coatings can be made very specific to a reflected wavelength or, by varying the layers'...
metallic coating A thin layer of metal deposited on the surface of a substrate. The film may serve as a reflector, beamsplitter, neutral density filter or electromagnetic interference filter.
dichroic coating A dichroic coating, also known as a dichroic filter or dichroic mirror, is an optical coating designed to selectively transmit or reflect certain wavelengths of light while simultaneously absorbing or transmitting others. The term "dichroic" comes...
