Description
The IR-CUT650 infrared cut-off filter blocks infrared light and passes only visible light below 650 nm. Because image sensors such as CCD and CMOS also respond to infrared light invisible to the human eye, IR contamination distorts captured images. This filter was developed exactly to solve that problem: it effectively blocks IR, removes interference and lets the sensor capture purer images. Used in CCD/CMOS lenses, security monitors, camcorder and camera lenses, phone lenses, scanners, visual doorbells, digital microscopes, digital binoculars and instrument heat insulation.
