Cold Mirrors/Filters

Cold mirrors are specialized dielectric mirrors. They can also be described as a dichroic filter that reflects the entire visible spectrum while transmitting infrared wavelengths. Similar to hot mirrors, cold mirrors can be designed for an incidence angle ranging between zero and 45 degrees, and are constructed with multi-layer dielectric coatings, in a manner similar to interference filters. Cold mirrors can work as dichroic beamsplitters within laser systems and are frequently used in lighting applications where excessive heat is not desired.
