Hot & Cold Mirrors
UQG supply Hot and Cold Mirrors that are used for controlling heat available to standard and custom specification or a range of dimensions.
Hot Mirrors
UQG Hot Mirrors Filters act as heat protection by adding the hot mirror in the path beam of the light source, so reducing the temperature. The hot mirror reflects IR and transmits visible. Our standard range is at 0° angle of incidence however we can supply 45° angle of incidence.

Cold Mirrors
UQG Cold Mirrors are suited for high power illumination systems when high temperature lighting is not desired. Separating the heat from light radiation they reflect visible light and transmit the infrared dividing the IR and visible more sharply.
