Dichroic filter
A dichroic filter, thin-film filter, or interference filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic reflectors tend to be characterized by the color of light that they reflect, rather than the color they pass. Used before a light source, a dichroic filter produces light that is perceived by humans to be highly saturated in color. Although costly, such filters are popular in architectural and theatrical applications. Used behind a light source, dichroic reflectors commonly reflect visible light forward while allowing the invisible infrared light to pass out of the rear of the fixture, resulting in a beam of light that is "cooler". Many quartz halogen bulbs have an integrated dichroic reflector for this purpose, being originally designed for use in slide projectors to avoid melting the slides, but now widely used for interior home and commercial lighting. This improves whiteness by removing excess red, however it poses a serious fire hazard if used in recessed or enclosed luminaires by allowing infrared radiation into those luminaires. For these applications non cool beam lamps must be used.
