DECTRIS EIGER2 S

DECTRIS EIGER2® S photon-counting X-ray detectors are the perfect choice if your research requires large-area, high-resolution beamline detectors, but not the ultimate speed. Like all EIGER2 detectors, this camera with 75-µm pixels delivers data with the highest spatial resolution. It includes two independent energy thresholds for spectral sensitivity, a single-pixel point-spread function for ideal counting statistics, and fast image readout with a frame rate up to 1 kHz. Equipped with a silicon sensor that is 450 µm thick, EIGER2 S detectors cover X-ray energies between 6 and 40 keV.

EIGER2 S detectors come in a variety of sizes. Their robustness, combined with excellent support, make EIGER2 S detectors the most reliable and future-proof tool for cost-conscious beamlines.

More & better data: these detectors have a large active area, two adjustable energy-discriminating thresholds, and a high count rate (over 10⁷ ph/s/pixel). There is no readout noise or dark current.
Affordable: EIGER2 S detectors offer high resolution for an unbeatable price per pixel.
Reliable: these detectors feature extremely stable performance and radiation hard design. Delivery terms are guaranteed, thanks to streamlined industrial production and top-notch support over the product’s entire lifetime.
