Encyclopedia > Cold mirror

Cold Mirror is a specialized dichromatic interference filter that operates over a very wide temperature range to reflect the entire visible light spectrum while very efficiently 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 be employed as dichromatic beamsplitters with laser systems to reflect visible light wavelengths while transmitting infrared. The term filter may refer to: A device to separate mixtures. ... The wavelength is the distance between repeating units of a wave pattern. ... A beam splitter is an optical device, that splits a beam of light in two. ...
