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. Metal coatings will modify the state of polarization of an incident beam of light and are therefore inappropriate for most polarization sensitive applications.
Enhanced metallic coatings provide greater reflection across the operating bandwidth. These coatings are enhanced by adding a multilayer dielectric stack.
We also offer a wide choice of standard metallic mirrors from stock.
