These are precision flat mirrors with a metallic gold coating. The gold layer is protected both underneath and above with dielectric layers which ensures good adhesion to the substrate and allows cleaning by normal laboratory methods. These mirrors have very high reflectivity from 0.65 microns through to the infrared spectrum.
