China Metallic Coating Mirrors Optical Mirrors

metallic coatings are excellent broadband reflectors.Auminium,silver or gold may be used. Aluminium has the broadest bandwidth extending from 200 nm to the near IR. Silver has the highest average reflectance and gold reflects well at longer wavelengths of infrared but cuts off at about 500 nm giving rise to its distinctive colour.

As metal coatings are prone to oxidation, they are normally protected with a thin layer of silicon dioxide. If a multilayer stack is used instead of a simple dielectric layer, it is possible to enhance the reflectance of metallic mirrors. "Enhanced" metal mirrors should be selected when the highest reflectance is required.
