Product Description

Absorptive filters/Infrared (IR) cut-off filters

Infrared (IR) cut-off filters are used with colour CCD or CMOS cameras to produce accurate colour images. An IR cut-off filter blocks the transmission of the infrared light while passing the visible light. This can be done with two optical techniques: absorption or reflection.

Absorptive filters are made with special optical glass that absorbs near infrared radiation. Reflection type filters are short-pass interference filters that reflect infrared light with high efficiency.

The absorptive filters are normally used for CCD cameras while the reflective IR Cut Off Filter is used for CMOS cameras.

As modern CCTV cameras and webcams all have a wide visible spectrum, they can all see IR light to some degree. This must be blocked to allow correct reproduction of colour from the camera, but of course it must not be blocked to allow the camera to see IR light for night vision.
