In the use of CCD or CMOS light sensing elements of digital cameras or digital video, because taking pictures is a discontinuity,when shooting images OLPF has the following two functions.
1. Because of Producing unnecessary optical information,it can prompt a stripe images that do not accord with the human visual sense. O.L.P.F is provided to eliminate the information function.
2. Because the CCD or CMOS light sensing elements can detect infrared part of the human eye can't detect when shooting photochrome, leading to distortion of image's color.So you have to remove the infrared part of the human eye cannot detect.The solution is required plating the IR CUT Filter on the surface of OLPF,that commonly called as "reflective";Or with a piece of phosphate glass (commonly known as blue glass), commonly called as "absorption" and at the same time adjusts color within the range of visible light (400 nm to 700 nm), that can make the image colour conforms to the feeling of the human eye.So you get true colors!
