IR Cut Off Filters

KUPO Optics provides IR Cut-off filters that effectively block infrared and transmit much of the visible light. It cuts off infrared so that the imaging will not be affected by infrared while presenting natural and accurate coloration in modern camera system.
 
Though we cannot see it, infrared exists in common light sources and can be detected by CCD or CMOS sensor. As those machine eyes can see infrared up to around 1000nm which will cause inaccurate coloration. Therefore, in order to assure image quality, infrared must be blocked. That is why IR cut-off filter is needed.
