At 0 ° incidence hot mirrors transmit the visible and reflect the near infra-red (heat) spectrum typically found in tungsten light sources. Hot mirrors therefore remove much of the energy that can cause heating in a lighting system. Hot mirrors can be used as an alternative to KG1 filters where... [See More]
