hot mirror, cold mirror and reflective mirror

Hot Mirror: A mirror like filter which reflects infrared light while transmisit visible light. Hot Mirrors are available in 0° or 45° angle of incidence options are ideal for decreasing the undesirable heat caused by infrared radiation. A multi-layer dielectric coating transmit 95% of visible light while reflecting over 95% of the NIR and IR making them suited for projection systems where heat build-up can lead to system damage.   Cold Mirror:A mirror like filter which transmits infrared light while reflecting visilbe light Cold mirrors have 0° and 45° angle of incidence and are ideal for decreasing the undesirable heat caused by infrared radiation. A multi-layer dielectric coating reflects 95% of visible light while transmitting over 95% of the NIR and IR. cold mirrors function satisfactorily iwht resistance to damage from ambient temperture of -45℃ to +232℃ and ideal for projection systems where heat build-up can lead to system damage Specifications Substrate  Float Glas…
