Metal Coated Mirrors, Protected Gold, ROC -200nm

We supply customers with metal coated mirrors, which can be customized upon request. Metal-coated mirrors exhibit relatively uniform reflectance over a wide range of wavelengths. They are almost insensitive to the angle of incidence and polarization state of light, so their reflection losses are much higher compared to dielectric thin-film mirrors.
