These Cold Mirrors (cold light reflective) have a 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 90% of the NIR and IR. Being made of BOROFLOAT glass, our Cold Mirrors' resistance to thermo damage from -45°C to 200+°C are ideal for projection systems, where heat build-up can lead to system damage. Custom size & AOI=0° are also available.
