Glod (Au) Mirror

Optical Mirror PARAMETER:
BRD Customized Optical Mirror. Protected gold is ideal for use in the IR wavelength range. A protective dielectric overcoat is layered over the gold to help protect it from damage and make cleaning easier. These optics provide >96% average reflectance from 800nm to 20μm.
The mirror  coated with metal (Au, Al, or Ag) over coated with silicon monoxide(SiO2). Metallic coatings have low peak reflectance, mechanical durability and damage threshold, but they have extremely broadband and low cost. They are insensitivity to angle of incident light and polarization.
