The C12741-11 is a near-infrared camera that employs a 640 × 512 pixel InGaAs sensor. -70 ˚C peltier cooling significantly reduces dark current which leads to improved image quality and allows imaging with long exposure time.
Unlike CCD or CMOS cameras, the C12741-11 can detect weak IR light with a high signal to noise ratio.
