冷熱反射鏡
They are coated with multi-layer all dielectric. Cold mirror reflects more than 90% of visible light(400nm-700nm) while allowing better than 80% transmission of near-infrared light when the angle of incidence is 45 degree. Cold mirrors are useful for illumination systems where high temperature lighting is not desired. Mirror will not be damaged by exposure to an ambient temperature.
