Hot mirrors reflect near-IR heat and transmit visible light at 0°
Cold mirrors reflect visible light and transmit near-IR heat at 45°
Available in 25.4 mm diameter and 50.8 mm square sizes.
Product Description
Our hot mirrors are heat-reflecting mirrors/filters designed to transmit visible wavelengths while reflecting near-infrared heat generating wavelengths. Our cold mirrors are heat-transmitting mirrors/filters designed to reflect visible wavelengths while transmitting near-infrared wavelengths. These filters can be used to remove heat from an optical system.

Product Detail
Hot mirrors are heat-reflecting
mirrors/filters designed to transmit visible wavelengths while
reflecting near-infrared, heat-generating wavelengths.
Cold mirrors are heat-transmitting mirrors/filters designed to
reflect visible wavelengths while transmitting near-infrared
wavelengths.
They can be used to remove heat from an optical system.
Hot mirrors are offered for use at 0° angle of incidence, while cold
mirrors are available for 45° angle of incidence. They are both
available in 25.4 mm diameter and 50.8 mm square sizes.
