Optical IR Filter

Detailed Product Description

Optical Filter >> Optical IR cut Filter >> infrared cut filter

Optical Infrared (IR) cut filters are used with color CCD/CMOS imagers to produce color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible light, which will increase the image quality and the true colour.

IR cut-off filters are mainly applied to CCD/CMOS Imaging System, such as Mobile camera, digital camera, PC camera, CCTVcamera, Visual phone and Video door phone etc.
