UV Hot Mirrors

Designed for a 0° angle of incidence, these UV Hot Mirrors’ multi-layer dielectric coating reflects infrared radiation, limiting heat buildup, while allowing UV and visible light to pass through. The fused silica substrate’s high transmission is ideal for projection and illumination systems, as well as in fluorescence applications that require the transmission of the UV excitation wavelength and the rejection of radiation harmful to temperature sensitive samples.

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.
