Zeiss Xradia Versa 520 3D X-ray Microscope


Materials Science, Life Sciences, Geological Sciences, Devices, Defect & Failure Analysis

  • Non-destructive imaging and reconstruction of buried features (pores, particles, defects, etc.)  
  • Phase contrast imaging for studying low Z or “near Z” elements
  • Diffraction contrast for the study of crystallographic orientation
  • Maintains resolution at a distance for non-destructive in situ imaging
  • Multiscale imaging, characterization of large samples at high throughput
