The 10CMR-45 Cold Mirror is a 25.4 mm diameter 45 mirror used as a heat control filter. . Our cold mirrors are heat-transmitting filters designed to reflect 400-700 nm visible wavelengths while transmitting 780-2500 nm near-infrared wavelengths. These filters can be used to remove heat from an optical system.
