EIGER2 R 500K puts an end to compromises in laboratory XRD. So far, all detectors demanded trade-offs between pixel size, active area, maximum count rates, and the capability for low- and high-energy discrimination. The Hybrid Photon Counting EIGER2 R 500K detector combines small pixels for high resolution, a large active area for efficient data acquisition, and unsurpassed count rates for accurate measurements of highest intensities. Dual energy discrimination in combination with simultaneous read/write allows for extensive background suppression and high dynamic range at the same time. High frame rates enable instrument manufacturers to make sophisticated 0D, 1D, and 2D data acquisition modes available. All these benefits come in a maintenance-free detector with DECTRIS‘ proven reliability.
