Metal Mirrors » Protected Silver

 

Protected Silver (PAG) Protected Silver has the highest reflectance of any protected metal coating in the visible, near IR and mid IR regions.

As an external reflector, silver is overcoated with one of several transmissive materials, depending on the wavelength region of interest. As an internal reflector, silver is overcoated with a black epoxy paint.

Protected Silver is not sensitive to wavelength, angle of incidence and polarization, so it is useful for a wide range of low to medium power monochromatic and polychromatic applications.

Durability meets MIL SPEC requirements.
