The C12741-11 is a near-infrared camera that employs a 640 × 512 pixels InGaAs sensor. -70 °C peltier cooling significantly reduces dark current which leads to improved image quality and also allows imaging with long exposure time.
The C12741-11 can detect weak IR light signal with high S/N ratio, of which image is difficult to take by CCD or CMOS camera and is suitable for use to evaluate solar cell or optical communication device analysis.
Features
- High sensitivity in near-infrared region
- Resolution: 640 × 512 pixels
- Low dark current with -70 °C peltier cooling (water cooling)
- Exchangeable between air/water cooling
