Applications

Day and Night filters pass the visible and 850nm of wavelength but cut off the NIR region from 950nm-1100nm. The filters are used in CCD or CMOS imaging system to produce a true color image. This filter allows the imager to work both at day and night. The application areas concern the secure monitoring, digital camera, visual telephone, visual doorbell, digital telescope and visual check-in recorder etc.
