Hot Mirror

INOUIRY

Hot reflectors are often used in light sources or optical signals that contain visible light and infrared light. Thermal reflectors can separate visible light from infrared light and collect only visible light, alleviating system temperature rise caused by infrared radiation.

Hor Mirrors are made of high-quality heat-resistant borosilicate glass. The surface is coated with a high-quality multi-layer dielectric film. The spectral characteristics of thermal reflectors are characterized by high transmittance in the visible light band and high reflectivity in the near-infrared light band. Using thermal reflectors can reduce heat and reduce the impact on overall system performance.
