POLLUX™ is the laboratory detector that redefines what you can expect from compact, energy-discriminating X-ray detection. Whether you’re integrating it into a next-generation instrument or want to run fast measurements of high-quality data in the lab, POLLUX delivers exceptional results - consistently and effortlessly.
Designed to deliver the optimal balance between energy resolution, count rate, and active area, POLLUX sets a new benchmark for real-world performance. With dual energy discrimination and excellent resolution, POLLUX effectively suppresses fluorescence and high-energy background, providing clearer signals and better peak-to-background ratios. Its large active area captures more of the beam and covers a wider angular range, enabling faster measurements and improved data quality. Thanks to its superior count rate capabilities, POLLUX enables accurate measurement of high intensities and supports absorber-free reflectometry experiments.
-
Excellent energy resolution and dual energy discrimination for effective background suppression.
-
Superior count rates for unparalleled dynamic range.
-
Versatile and easy to integrate thanks to compact design and passive air cooling.

Techniques

Powder X-Ray Diffraction
Modern powder X-ray Diffraction has a high: throughput, sensitivity to impurities, reliability, and temporal and angular resolution. Synchrotron beamlines and laboratory instruments are equipped with 1D and 2D hybrid-pixel X-ray detectors to cover a wide energy range: from 4 to 80 keV.

Residual Stress Measurements
Limitations of samples, such as fluorescence, size, and changes in time, can be overcome by implementing photon-counting X-ray detectors in various setups. These range from synchrotron sources to portable X-ray diffractometers.

Wide-Angle X-ray Scattering (WAXS)
Wide-Angle X-ray Scattering (WAXS) probes crystalline and partially-ordered samples down to their atom-atom spacing. It is readily combined with Small-Angle X-ray Scattering (SAXS), even when using the same photon-counting detector.

Wavelength Dispersive X-ray Fluorescence (WD-XRF)
The key feature of the WD-XRF technique is its high resolution. Can the resolution be increased further, without compromising measurement speed or sensitivity to weak signals?

EXAFS & XANES
EXAFS and XANES have come to laboratory spectrometers, and the synchrotron techniques are moving forward. What is the role of hybrid-photon-counting detectors in this?
