The 20CMR-45 Cold Mirror is a 50.8 x 50.8 mm square 45° mirror used as a heat control filter. Our cold mirrors are heat-transmitting longpass filters designed to reflect 400-700 nm visible wavelengths while transmitting 780-2500 nm near-infrared wavelengths. These filters can be used to remove heat from an optical system.


20 cmr-45冷镜是一个50.8 x 50.8毫米平方45°镜子用作热控制过滤。我们的冷镜是热透射长通滤波器,设计用于反射400-700纳米可见波长,同时透射780-2500纳米近红外波长。这些过滤器可以用来除去光学系统中的热量。
