Hot Mirror

Hot Mirror

Hot mirror is used to protect optical systems by reflecting infrared light back into a light source, while allowing visible light to pass. Hot mirror can be designed to be inserted into the optical system at an incidence angle varying between zero and 45 degrees. The wavelengths reflected by this special mirror ranges from about 750 to 1250 nanometers. By transmitting visible light wavelengths while reflecting infrared, it is useful when heat build-up of illumination source would damage components or the components would be used in fluorescence microscopy.
