C12741-11 InGaAs Camera from Hamamatsu Photonics

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
