Hot and Cold Mirrors

 High Performance Cold Mirror

High Performance Cold Mirror

Our cold & hot mirrors are made of high quality heat-resistant borosilicate glass material. The surface is coated with high quality multi-layer dielectric coating. Hot Mirrors have a high transmission of visible light and high reflection of IR wavelengths. Cold Mirrors have a high transmission of IR wavelengths and high reflection of visible light. Hot mirrors can reduce heat and minimize impact on overall system performance. For high power illumination, additional air cooling is recommended.
