Cold Mirror

Cold Mirror

A cold mirror is designed to reflect visible light and transmit infrared radiation/energy (heat). As a result, the visible light is fully available for the lighting application while reducing up to 90% of the reflected heat. They are a very efficient way to reduce ambient heat optically and are a very effective mirror to the visible spectrum.

Cold mirrors are frequently applied to reflectors that are located close to the source. EMF can apply these films to your reflector or can source reflectors and apply the coating to meet your requirements.

EMF has supplied 800,000 cold mirrors to a global automotive components manufacturer for Head-Up Displays (HUDs)
