Product Description
At 45° incidence, Cold Mirrors reflect the visible spectrum of light and transmit the near infra-red, which contains the thermal energy i.e. Heat. Cold Mirrors are therefore another excellent alternative for transmitting the near infra-red spectrum. Cold Mirrors have a sharpe cut off between IR and Visible because they have a dielectric coating that can be controlled.
