High quality optical mirrors are available for use with light throughout the UV, VIS, and IR spectral regions. The metallic mirror coatings have high reflectivity over the widest spectral region while the broadband dielectric mirrors have a narrower spectral range of operation; the average reflectivity throughout the region is greater than 99%. Hot, cold, backside polished, ultra fast, and laser line dielectric coated mirrors as well as D-shaped mirrors are available for more specialized applications.
