ARINA

This ultra-fast 4D STEM detector does not compromise on dynamic range or sensitivity.

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.

  • Fast and sensitive: Even at a frame rate of 120 kHz, DECTRIS ARINA can count every single electron—up to 10 pA/pixel.
  • Flexible: Featuring silicon (Si) or high-Z sensor materials, DECTRIS ARINA covers a wide range of energies, from 30 to 300 keV.
  • Empowering: Our team of like-minded scientists and engineers is here to help you get the most out of your setup.
