Hot Mirrors are designed to remove (reflect) infrared heat in an optical system and transmit visible energy. The HM-VS-1150 Hot Mirror, formerly known as Hot Mirror #102, design has been optimized to have much higher and color neutral visible transmission than conventional Hot Mirrors. The HM-VS-1150 color neutral Hot Mirror is ideal for use in fiber optic illuminators, movie and slide projectors or any application where color projection is critical. The HM-VS-1500 Super Heat Buster® Hot Mirror offers protection from ultra violet radiation and extended I.R. reflection for extreme temperature appli-cations. For conventional heat/light separation see HM-VS-950 Commercial Hot Mirror.
