Cold Mirrors


Cold Mirrors reflect the visible spectrum of light and transmit the near infrared, which contains the thermal energy i.e. Heat, therefore they can be used as an alternative for transmitting the near infrared spectrum.

Cold Mirrors have a sharp cut off between infrared (IR) and Visible because they have a dielectric coating that can be controlled. Cold Mirrors are often used with tungsten lamps which are the source in a projector or lighting system.
