Infrared cut-off filters, sometimes called IR filters or heat-absorbing filters, are designed to reflect or block mid-infrared wavelengths while passing visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating. There are also filters which are used in solid state (CCD or CMOS) video cameras to block IR due to the high sensitivity of many camera sensors to near-infrared light. These filters typically have a blue hue to them as they also sometimes block some of the light from the longer red wavelengths.
It's fabricated by special blue glass (BG39 from Schott or equivalent). The glass will absorb IR wavelength and let visible light pass.
Application:
Digital cameras,CCTV surveillance camera,security camera systems,mobile phones,PC cameras,webcam, digital imagers,digital vidicons,color imager,IR photometric systems,remote control units,scanners.
