Product introduction:

      PXE303 camera is assembled with a large area scientific CCD sensor with 4K x 4K pixels, with a pixel size of 12 μm, a back illuminated structure, and a quantum efficiency of more than 90% (500nm-650nm band). It has 4 readout channels. 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.
