C-RED 2 ER is a highly sensitive extended InGaAs camera series for extended SWIR imaging and opens new imaging and sensing opportunities for life science, research, laser measurements, and industrial applications.

C-RED 2 ER are VGA (640 x 512 pixels) detectors with a 15 μm pixel pitch for high resolution, and with peak quantum efficiency > 70%. All models are able to run at 600 fps, full frame, and up to 32066 fps in cropping mode. In addition, all models have an integrated two-stage thermoelectric cooler, which enables a cooling capability up to 60°C.

C-RED 2 ER is available with two options of InGaAs detectors with shifted sensivity ranges:

  • C-RED 2 ER 1.9 μm is sensitive in the range of 1.1 to 1.9 μm
  • C-RED 2 ER 2.2 μm is sensitive in the range of 1.2 to 2.2 μm

C-RED 2 ER 1.9 μm and C-RED 2 ER 2.2 μm are complementary to C-RED 2 in terms of sensitivity, as they cover the high end of the SWIR spectrum. The C-RED 2 ER 1.9 μm achieves a readout noise < 50 e- while C-RED 2 ER 2.2 μm readout noise is < 40 e-.

The development of extended range detectors based on InGaAs technology is a recent breakthrough in imaging. With a double thermoelectric cooling system, the camera is a straightforward solution for imaging in the far end of the SWIR spectrum without the cryogenic cooling required for HgCdTe.
