Product Details

UV Enhanced Aluminium mirrors flat mirrors metal mirrors

Just as with anti-reflection (AR) coatings, metallic mirror coatings are also designed for different regions of the spectrum

Changchun Ruiqi offers a series of protected metallic coatings capable of providing high reflectance values for applications using wavelengths ranging from 250nm to beyond 10μm. Our standard metallic mirror coatings include Protected Aluminum, Enhanced Aluminum, UV Enhanced Aluminum, Protected Gold and Protected Silver. Protected Aluminum and Enhanced Aluminum are typically used for visible applications. UV Enhanced Aluminum can be used for UV and visible applications. Protected Gold offers high reflectance for Infrared or near-Infrared wavelengths. Protected Silver provides the highest reflectance between 500-800nm but is best suited as a rear surface reflector due to its sensitivity to tarnishing.
