Metallic Mirror
    Broadband Dielectric Mirror (0 - 45 degree )

Metallic Mirrors have high reflection in broad spectrum from 0.4 um to 20 um Metallic Mirrors have dielectric layer over the metal layer for protecting the coating from oxidized in air or from scratched and for increasing reflectance, so this Metallic mirrors are called Enhanced Metallic Mirror.

Coating Type
Protective Coating has a dielectric layer over metallic layer for protecting the metal
coated layer.
Enhanced coating has a dielectric multi-layer over metallic layer for increasing
reflectance of a particular wavelength
