Large-Format CCD Cameras for X-Ray Diffraction Imaging

Princeton Instruments, the world’s leading developer and supplier of ultra-low-noise, deep-cooled scientific CCD cameras, is pleased to offer our popular Quad-RO series for indirect imaging of x-rays. Using a variety of phosphor screens, these thermoelectrically cooled, large-image-area, 4-readout-port cameras delivers optimized performance and impressive application flexibility in the x-ray energy range from ~3 KeV to >20 KeV.

  • Front-illuminated CCD with 2084 x 2084 pixel array and 24 x 24 µm pixels resolution with  24 x 24 µm pixel size (ITO technology)
  • Sensitivity in X-ray energy range from ~ 3 KeV to >
    20 KeV
  • Industry-standard FireWire interface
  • Multiple-port readout for high frame rates
  • Unique mechanical design for easy phosphor replacement
  • Full experiment control via 64-bit LightField software (optional)

Streak Tube Readout
Streak tube readout is commonly used to obtain intensity vs. spatial or spectral information over time periods of picoseconds to nanoseconds.

Micro-Computed Tomography
Micro Computer Tomography is a unique technique for the noninvasive, nondestructive 3D characterization of materials down to a micrometer scale.


Application Notes

X-ray µCT provides nondestructive, high-resolution 3D imaging for research and industrial applications
X-ray computed microtomography uses high-resolution, widedynamic- range CCD cameras, high-resolution scintillators, either synchrotron x-ray sources or microfocus x-ray tubes, and software algorithms designed to reconstruct 3D images.

X-ray Phase-Contrast Imaging
Early-stage tumors and associated vascularization can be visualized via x-ray phase-contrast imaging.

An all-optical Compton source for single-exposure x-ray imaging
Researchers from CNRS—Ecole Polytechnique—Université Paris-Saclay, France and Centro de Laseres Pulsados, Parque Cientfico, Salamanca, Spain incorporated a Quad-RO x-ray camera in their experimental setup to present results on a single-pulse scheme that uses a plasma mirror to reflect the drive beam of a laser plasma accelerator and to make it collide with the highly-relativistic electrons in its wake.
