IR Blocker : We can supply all kinds of IR Blocker (IR-Cut Filter ) according to your requirements.

IR Blocker : 

    The IR Blocker which also called IR Cut Filter is normally used in solid state (CCD or CMOS) video cameras to reflect or block IR wavelength while passing the visable light. It can be used on digital mobile telephone, CCTV (Surveillance cameras), PC cameras, videophone etc. The IR-CUT Filter is basically a high quality optical glass substrate which had a IR-CUT coating on its surface. It could effectively repress the wave disturbance which caused by the light of near-infrared light, to make the image clearly and steady.
