Through infrared acrylic filter is acrylic as the base material of black or deep red material. This material is characterized by the ability to give black vision in the visible range (visible light transmittance less than 1 between 400 and 700nm), but can penetrate the near infrared region of wavelengths above 720 to 1100nm, with transmittance ranging from 80 to 95 depending on component thickness, operating band and color requirements. It IS WIDELY used IN communication components with infrared transmittance, which can easily cover the internal structure because of the black visual color while helping to pass the infrared signal. A large number of mobile phones, computers, home appliances, automobiles, infrared touch screen and other infrared signal transmission or infrared window. Infrared permeable acrylic filters are produced according to customer requirements. Through infrared acrylic plate working principle: a variety of infrared induction receiver, the main function is to filter out visible light energy stray light, through as much as possible near infrared, not broken, easy to cut. The cost is low. And non-staining, good light transmission.
