EsteemOpitcs provides metallic high reflective coatings made of Au, Ag and Al. These coatings are applied where a consistent high reflection over a wide spectral range is necessary. Their reflectivity is not higher than dielectrics HR coatings, but their HR spectrum can cover the near-UV, visible and near-IR. In order to prevent these metallic coatings from oxidization, these coatings have dielectric overcoat.
