Cold mirror

These cold mirrors provide two incident angles, 0 ° and 45 °, which are very suitable for reducing the harmful heat generated by infrared radiation. The multilayer dielectric film can reflect 90% of visible light and transmit more than 80% of NIR and IR. The function of the cold mirror is satisfactory and can resist ambient temperatures ranging from – 45℃ to + 232℃
