Metallic Mirror

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

General Specification

  • Substrate
    • Optical glass (Range : 400mm to1200nm)
    • Fused Silica (Range : 250mm to 1200nm)
  • Size Tolerance : +0.0mm,-0.25mm
  • Thickness : 2.0mm (nominal)
  • Surface/Coating Quality : F/F per MIL-F-48616
