optical telescope flat mirror

Optical Telescope Flat Mirror   HR coatings are affected by the incidence angle of the light. When used away from normal incidence, the reflective range shifts to shorter wavelengths, and becomes polarization dependent. This effect can be exploited to produce coatings that polarize a light beam.       Product Description Optical Telescope Flat Mirror :
