Environmental Resistance

CCL Hot Mirrors can withstand severe exposure to heat and ultraviolet radiation because they are made entirely of glass and stable clear oxides. Damage resistance to rain, humidity and chemicals exceeds MIL-C-675-C, which has long been used to specify shipboard optical equipment. This product is suitable for space or underwater application.

Dielectric Beamsplitters


Divide transmitted and reflected images without absorption (of light) loss. Dielectric beamsplitters are superior to typical two-way mirrors, where the metal absorbs a lot of the transmitted light (brightness). Typically used for special effects. Applications include teleprompters, movie making, microscopes, heads-up displays, rifle sights, camcorders, and industrial photo processing.
