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

Metallic coatings 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.
