DECTRIS POLLUX X-Ray Detector for Laboratories - Versatility Meets Performance

The small X-ray detector POLLUX™ combines unmatched versatility with exceptional performance. POLLUX reliably and easily produces outstanding findings, whether it is integrated into next-generation equipment or used for quick measurements of high-quality data in the laboratory.

POLLUX is designed to provide the best balance of energy resolution, count rate, and active area, establishing a new standard for real-world performance. With dual energy discrimination and superior resolution, POLLUX efficiently suppresses fluorescence and high-energy background, resulting in clearer signals and higher peak-to-background ratios.

Faster measurements and better data quality are made possible by its large active area, which collects more of the beam and covers a broader angular range. POLLUX enables absorber-free reflectometry and allows precise measurement of high intensities thanks to its improved count-rate capabilities.

  • Outstanding dual energy discrimination and energy resolution for efficient background reduction
  • Unmatched dynamic range at superior count rates
  • Compact design and passive air cooling make it versatile and simple to integrate
