- Description
- Specifications
Metal-coated mirrors exhibit relatively uniform reflectivity over wide wavelength range. They are pretty much insensetive to angle of incident and polarization state of the light. Therefore, these mirrors are preffered for broadband and white-light applications, thus their reflection losses are higher compared to dielectric thin-film mirrors.
