Mettallic Mirror

With aluminium (Al), silver (Ag) or Gold (Au) coating, the mirror show high relfection perfance for very wide broadband. Generally, we over coat the protective SiO2 or MgF2 layer outside the metal layer to avoid the damage from the environment.
Metal coating is less sensitive to variations than dielectric coatings ,in incident angle, polarization, and wavelength

Coating Type	Description
UV enhanced Al+MgF2 coating	Al coating has higher reflection than Ag or Au coating at UV to visible range. By special design, Tempotec can coat the UV enhanced Al+MgF2 with Ravg>85%@250nm~700nm.
Protective Al+SiO2 coating	Ravg>90%@400nm~10.0um
Protective Ag+SiO2 coating	Ravg>95%@600nm~10.0um
Bare gold coating	Ravg>96%@700nm~20um
Protective gold coating	Ravg>95%@700nm~1700nm & Ravg>98%@2um~16um
