High Reflective Coatings
 

High Reflection (HR) coatings, including high reflection dielectric coatings and Metallic coatings, provide high reflection in some wavelength range, and are widely used in laser system and other optical elements. HR coating provides more effective and efficient spectral performance due to the low absorption properties. These mirror coatings can also be further customized to provide additional high pass or low pass wavelength performance in addition to the specified reflection band.
