• Ideal for Minimizing Heat Build-Up
TECHSPEC® High Performance Hot Mirrors feature
a multi-layer dielectric coating optimized for greater
than >85% transmission of visible light and greater
than 95% reflection of IR wavelengths. For high power
illumination, forced air cooling is recommended.

• Ideal for Reducing Heat
• Reflects 90% of the NIR and IR
• Transmits 85% of Visible Light
Hot Mirrors are available in 0° or 45° angle of incidence options and are ideal for decreasing the undesirable
heat caused by infrared radiation. A multi-layer dielectric coating transmits 80% of visible light while reflecting
over 90% of the NIR and IR, making them suited for projection systems where heat build-up can lead to system
damage. Note: When using high power illumination, forced air cooling is recommended.
Hot mirrors are crucial in many projection and illumination systems where high levels of heat can quickly
damage sensitive components. Hot mirrors are specially coated to transmit visible light while reflecting the
NIR, a major attributor to heat generation. By using a hot mirror, heat levels are limited with minimum impact
on the overall system performance.
