Product introduction:

      PXE231 camera  is assembled with a large area scientific CCD sensor with 4K x 4K pixels, with a pixel size of 15 μm and a back illuminated structure. The quantum efficiency is more than 90% (500nm-650nm band). At the same time, a deep depletion CCD is available, with a peak QE of more than 95%. It has four readout channels. The readout noise is less than 5e- at 100kHz and less than 9e- at 500KHz. The camera adopts vacuum sealing technology, with double cooling of air cooling and water cooling, which can achieve deep cooling with temperature difference of 75 ℃, and has extremely low readout noise and dark current noise. Applications include: Astronomical optical band imaging, particle physics imaging, etc.
