The pco.edge 4.2 bi XU is based on a back illuminated sCMOS sensor with a very specific coating which allows applications in the visible light down to extreme UV (EUV) and soft X-ray radiation. The camera is adapted for ultra-high vacuum operations and has been characterized using soft X-ray in the energy range from 30 eV to 1000 eV. The image sensor features 2048 x 2048 pixel with a pixel size of 6.5 µm x 6.5 µm and allows full frame acquisitions at 48 Hz with a dynamic range of 88 dB at a noise level of 1.9 e - . The camera is compact and offers various software integration options.
