  • Small pixel size less < 26 microns pixel size at the detector input
  • Cooled CCD sensor with 55 degrees C delta T
  • Software switchable 10 and 20 MHz scanning frequencies
  • Small area sensor with taper input varying from 5.6 mm up to 40 mm diagonal

PSL has supplied X-ray High Resolution CCD cameras for the last 7 years to end users and OEMs. A selection of high responsitivity CCDs, combined with low noise characteristics, enables optimum photonic collection with best possible signal to noise ratio. Special read whilst expose mode allows 100% shutterless duty cycle and high sensitivity operation in low light level conditions.

Applications:

  • • Microdiffraction
  • • X-ray imaging
  • • X-ray micro CT
  • • Laue imaging
  • • Protein crystallography at up to 50 keV
  • • Gisaxs
  • • Powder Diffraction
  • • Non Destructive Testing
  • • Phase Contrast Imaging
  • • Small animal imaging
