Black infrared transparent acrylic lenses are black or deep red materials based on acrylic. The characteristic of this material is that it gives black vision in the visible light range (the visible light transmittance of 400-700nm is less than 1%), but it can transmit through the near infrared region with wavelengths above 800-1600nm. The infrared transmittance can range from 80% to 93% according to the thickness of the component, the working band and the color requirements. Widely used in communication components that need infrared transmission characteristics, the internal structure can be easily covered because of the visual black when passing infrared signals. A large number of mobile phones, computers, home appliances, cars, infrared touch screen, such as infrared signal transmission or infrared window. Materials can be cut by laser cutting machine, special-shaped and injection molded. Main application fields: Sanitary equipment induction window, intelligent lighting induction window, remote control window, electrical equipment induction window, infrared induction window of instruments and meters, infrared butt joint of security laser night vision device, biological red film identification system, industrial equipment protection window, etc.
