Our best grade Hot Mirror formerly known as Hot Mirror #101. For applications where extreme infrared heat and damaging U.V. radiation are of concern; the U.V. Hot Mirror is an ideal solution. It rejects all U.V. radiation down to 200 nm, transmits the visible spectrum and has extended I.R. heat reflection out to 1500 nm. Should color temperature be critical see HM-VS-1150 Color Neutral Hot Mirror. For conventional heat/light applications see HM-VS-950 Commercial Hot Mirror.
