How Non IR Len, IR Lens Work
Day & Night cameras are normally used in near-infrared ( NIR ) or infrared ( IR ) at night. If we use a Non IR lens with a day & night camera, the image will be out of focus ( shifting ) at night.
Our special optical designs with broad band co-focusing technology based on special glass material minimize light dispersion. As a result , refocusing is not required when the camera is used under NIR or IR. The special design makes the lens to deliver perfect focusing either under visible light or under IR illumination circumstances.
