IR-CUT Optical Filters, Infrared Cutoff Filters


Features and Applications of IR-CUT Filters

IR-CUT optical filter is made of optical glass like N-BK7 or B270, coated with an optical cutoff and or anti-reflection coating. It is allowing visible light to pass through and cutoff or reflection of infrared light. So that through the camera after the light wave filter to the high-frequency segment, only a certain range of low-frequency light waves through. The addition of optical glass cell phone filter between lens and CCD or CMOS image sensor can effectively suppress ripple disturbance caused by light wave passing above CCD or CMOS image sensor space frequency, and effectively suppress infrared light wave, improve the effective resolution and color reduction of color CCD and CMOS image sensor, make the image clear and stable. IR-CUT optical filters are mainly used in digital cameras, mobile phones, computer cameras, monitors, videophone and so on.

Creator Optics can provide various customized IR-CUT optical filters according to customer requirements. There are following available types of IR-CUT optical filters:
