Broadband Dielectric Multilayer Mirror

This broadband dielectric multilayer mirror has two types of oxide dielectric alternate multilayer films with different refractive indices that were vapor deposited on a flat substrate using ion-assisted film-forming technology.
This product is easy to handle due to a high reflectivity of 99% and above in comparison to metal mirrors, and an equivalent mirror surface solidity to glass.

- High reflectivity of 99% and above in a wide range wavelength, such as 400-1200 nm or 600-1700 nm
- Capability to use an incident angle range of 0-50 degrees
- High reflectance from both P and S polarized lights
- Almost no deterioration due to aging
- Capability to be used under high temperature and high humidity
- High CW laser proof stress due to almost no absorption loss in comparison to metal mirrors
