Description:
IR Blocker :We can supply all kinds of IR Blocker (IR-Cut Filter ) according toyour requirements.
IR Blocker :
The IR Blocker which also called IRCut Filter is normally used in solid state (CCD or CMOS) videocameras to reflect or block IR wavelength while passing the visablelight. It can be used on digital mobile telephone, CCTV(Surveillance cameras), PC cameras, videophone etc. The IR-CUTFilter is basically a high quality optical glass substrate whichhad a IR-CUT coating on its surface. It could effectively repressthe wave disturbance which caused by the light of near-infraredlight, to make the image clearly and steady.
