DECTRIS ARINA® retractable, electron-counting detector was specifically developed for 4D STEM applications. Featuring a new ASIC, it combines an extreme speed of up to 120,000 frames per second with a high dynamic range and noise-free readout, thus enabling high-quality data acquisition at the native speed of a conventional STEM measurement. Thanks to DECTRIS’ hybrid-pixel technology, ARINA can employ different sensor materials and perform optimally in the whole energy range of 30-300 keV.

DECTRIS ARINA fits the bill for a broad spectrum of 4D STEM applications with dwell times below 10 μs, from crystalline-phases and orientation mapping to ptychography - including flexible STEM images reconstruction with virtual detectors.
