POLLUX
Designed to deliver the optimal balance between energy resolution, count rate, and active area, POLLUX sets a new benchmark for performance and versatility.
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.
