IR Block Filter

IR-cut filter(ICF) is a short pass (or called a lowpass filter) filter that blocks infrared light and transmits the visible range light(400~700nm).

Infrared (IR) cut-off filters are used with color CCD or CMOS imagers to produce true color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible. This can be done with two optical techniques: absorption or reflection. Absorptive filters are made with special optical glass that absorbs near infrared radiation.


If you need this absorptive IR blocking filter, please choose our blue glass filter. Reflection type filters are essentially short-pass interference filters that reflect infrared light with high efficiency.

 

Application:
Digital cameras, CCTV surveillance camera,security camera systems, mobile phones, PC  cameras, webcam, digital imagers, digital vidicons, color imager, IR photometric systems, remote control units, scanners.


Substrate:
Soda-lime glass,K9
