Metallic Coatings

  • protected aluminium
  • protected silver
  • protected gold
  • enhanced aluminium

Protected metallic coatings provide a moderate level of reflection over a very broad spectral range and are widely used as mirrors. These coatings are protected by a thin layer of dielectric material in order to make them durable. Enhanced metallic coatings provide greater reflection across the operating band width. These coatings are enhanced by adding a multilayer dielectric stack.
Metal coatings will modify the state of polarization of an incident beam of light and are therefore inappropriate for most polarization sensitive applications.
