Metallic Coatings | Shanghai Optics

Metallic Coatings, provide high reflection in some wavelength range and are widely used in laser systems and other optical elements. Metallic Coating provides more effective and efficient spectral performance due to the low absorption properties. These mirror coatings can also be further customized to provide an additional high pass or low pass wavelength performance in addition to the specified reflection band.
