X-ray Cameras for Low-Flux Applications

PIXIS-XB thermoelectrically cooled, direct-detection cameras are ideal for low x-ray flux imaging and spectroscopy in the energy range from ~3 keV to ~20 keV. These cameras are available with back-illuminated, deep-depletion 1340x400 and 1024x1024 pixel arrays, as well as front- and back-illuminated, deep-depletion, 1340x1300 pixel arrays. A thin beryllium window in front vacuum-seals the unit for deep cooling, protects the CCD, and reduces background by filtering low-energy x-rays.

PIXIS-XB cameras offer the following salient features:

  • Sensitivity in the x-ray energy range from ~3 KeV to ~ 20 KeV 
  • Vacuum chamber design with beryllium (Be) window
  • Flexible dual-amplifier readout design
  • High-speed USB 2.0 interface
  • Full experiment control via 64-bit LightField software (optional)


High-performance cameras for low-flux applications.

Labs around the world rely on Princeton Instruments PIXIS-XB systems to deliver the excellent performance and flexibility required to conduct leading-edge research involving low x-ray flux imaging and spectroscopy. Applications include x-ray photon counting, x-ray diffraction, x-ray spectroscopy, x-ray intensity fluctuation spectroscopy (XIFS), x-ray photon correlation spectroscopy (XPCS), and x-ray lithography.
