It is allows visible light to pass through and cutoff or reflection of infrared light. The IR-CUT optical filter is mainly used in digital cameras, mobile phones, computer cameras, monitors, videophone and so on. 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.
It's one of IR cut filtercustomized by our customer, we could also manufacture and design otherfilter as per your requirement.
