The filter for SLR cameras uses the principle of crystal birefringence to match the large-area CCD imaging sensor, effectively controlling the moiré fringe caused by the passage of light waves higher than the spatial frequency of the CCD image sensor, and effectively controlling the infrared light waves to make the image more Clear and stable.
Optical Low-Pass Filter (OLPF) is a core part in digital cameras, video cameras and the CCTV camera optical system. It can effectively prevent the false color and corrugation of CCD/CMOS image sensor due to the pixel interval, and make the image clearer and more stable.
