Details

High performance hot mirrors often contain visible light and infrared light in light sources or signals. Cold/hot mirrors can separate visible light from infrared light, only capturing visible light, and alleviating system heating caused by infrared radiation.
The cold and hot reflectors provided by Guangtan Intelligent are made of high-quality heat-resistant borosilicate glass material. The surface is coated with high-quality multi-layer dielectric film. The spectral characteristics of a thermal reflector are characterized by high transmittance in the visible light band and high reflectivity in the near-infrared light band. The spectral characteristics of a cold reflector are characterized by high reflectivity in the visible light band and high transmittance in the near-infrared light band. The use of thermal mirrors can reduce heat and minimize the impact on overall system performance.
Guangtan Intelligent is a standard supplier of reflective mirror optical products. We not only provide a large number of standard reflective mirrors in stock, but also customize reflective mirrors according to your needs.
