High reflective mirror optical thin film coating
Optosigma Corporation

We offer narrowband and broadband dielectric high reflecting coatings as well as a range of metal coatings. Laser Line HR Coatings are offered for all major laser wavelengths in the range of 193 to 2100nm. Broadband HR Coatings are offered for a selection of bandwidths. They provide a very high degree of spectrally neutral reflection and represent the ultimate in optical mirror coatings. Most of the coatings listed are for use at 45 degrees angle of incidence, but we do offer a selection of Broadband, Normal Incidence HR Coatings. Other normal incidence coatings can be provided on special request.

Metal coatings, such as Protected Aluminum, Protected Silver or Protected Gold provide reflectance over an extremely broad spectral range. These coatings are protected by a thin layer of dielectric material in order to make them durable. It is also possible to enhance the performance of metal coatings by adding several dielectric layers over the metal coating.
