PARAMETER:

Ecoptik provides metal coated Front Surface Mirrors. The front surface 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.
