Silver-coated mirrors have the highest reflectivity of all metal-coated mirrors in the visible wavelength range. Silver offers high reflectivity from 450 nm - 20 µm. In order to protect the mirrors from oxidation, they have an overcoat of SiO2. Though the overcoat helps to protect silver from tarnishing, high humidity environments should be avoided.
The plot to the right shows the measured reflectance of protected silver as a function of wavelength. The shaded region denotes the range over which we recommend using these optics. Data was obtained at a 45° angle of incidence.
