♦ UV-IR Cut Off Filters 

(UV-IR Cut Off Filter,UV-IR Blocker,UV / IR CUT Blocking)

UV IR Cut is a specialized filters that has the ability to cut both UV rays below 400nm and IR rays above 680mn leaving just the light rays in the visible spectrum passing through the filter and into the camera.This filter is used on a digital camera and the video
