The 20HMS-0 Hot Mirror is a 50.8 x 50.8 mm square 0° mirror used as a heat control filter. Our hot mirrors are heat-reflecting shortpass filters designed to transmit 420-690 nm visible wavelengths while reflecting 725-1550 nm near-infrared heat generating wavelengths. These filters can be used to remove heat from an optical system.
