A series of research and development have been carried out in the application fields of infrared window, infrared camera, infrared touch, infrared monitoring, infrared thermal imaging, infrared sensor, smart home, robot, security and so on. Infrared transparent plastic particles, infrared filter plates, filters, and infrared filter films have been developed. The surface color of the material is black, white, deep red or brown, and various other color properties can be customized according to customer requirements. The company’s infrared transmission materials have stable optical performance, super penetration, strong anti-interference ability, good shielding to visible light and strong light, and can penetrate the near-infrared region with wavelengths above 575nm-1600nm. The infrared transmittance is based on the component’s The thickness, working band and color requirements, the transmittance can reach 88%-94%.
