Overview: Metal Coated Flat Mirrors are convenient in that they are extremely broadband and can be
used at any angle of incidence. We offer Gold, Silver and Aluminum
high reflection coatings formed by vacuum deposition. All metallic
reflectors can be over-coated with dielectric film of MgF2 or SiO2
in order to prevent oxidation of the metallic surface and provide
abrasion resistance. - Protected Gold provides excellent, broadband infrared high
reflectance
- Protected Silver provides higher reflectance than aluminum
throughout the visible and near IR
- Protected Aluminum is economical solution for VIS applications
- UV enhanced Aluminum provides good reflectance over a wide range
and are mainly used in UV applications.
