C-RED 2 ER: high speed extended range InGaAs cameras

MCT-based cameras are very competitive when it comes to ultra-low light imaging, however it is crucial for less demanding applications to have a non-cryogenic and cost-effective solution. Progress in band-gap engineering has enabled to shift the detection cut-off wavelength of InGaAs by tuning the indium composition of the InxGa1-xAs compound. Operating with a double TEC coupled to air and water cooling, the C-RED 2 Extended Range cameras are an alternative to MCT for specific applications in astronomy and free space optics. We will present the performances of these new VGA extended range InGaAs cameras with sensitivity from 1.1 mu m to 1.9 mu m and from 1.2 mu m to 2.2 mu m.
