InGaAs camera

C12741-11

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.

Features

  • Resolution: 640 × 512 pixels
  • Low dark current with -70 °C peltier cooling (water cooling)
  • Interchangeable between air/water cooling

Applications

  • Solar cell evaluation
  • Semiconductor failure analysis
  • LED failure analysis
  • EL/PL image acquisition
  • Optical communication device analysis
  • Non-invasive in-vivo imaging
