Dichroic mirror
Dichroic mirrors (commonly called cold mirrors) are usually used behind a light source to reflect visible light forward while allowing the invisible infrared light to be emitted from the rear of the luminaire. This arrangement allows intense illumination with less of the object being illuminated. Whiteness is improved by removing excess red; however, if infrared is used in recessed or enclosed luminaires, it will create a serious fire hazard by radiating into these luminaires.
