DECTRIS ARINA Ultra-Fast 4D STEM Detector

The DECTRIS ARINA is an ultra-fast 4D STEM detector that does not trade off on sensitivity or dynamic range.

The DECTRIS ARINA retractable, electron-counting detector is designed to handle 4D STEM applications. It features a new ASIC and combines an extreme speed of up to 120,000 frames per second with a noise-free readout and a high dynamic range. This allows superior-quality data acquisition at the conventional speed of a traditional STEM measurement.

Owing to DECTRIS’ hybrid-pixel technology, ARINA can utilize various sensor materials and runs optimally in the entire energy range from 30 to 300 keV.

DECTRIS ARINA is ideal for a wide range of 4D STEM applications with dwell times lower than 10 μs, spanning from crystalline phases and orientation mapping to ptychography, including versatile STEM image reconstruction using virtual detectors.

  • Flexible: Comprising silicon (Si) or high-Z sensor materials, DECTRIS ARINA encompasses an extensive range of energies from 30 to 300 keV.
  • Rapid and sensitive: The DECTRIS ARINA can count every single electron—up to 10 pA/pixel even at a frame rate of 120 kHz.
  • Empowering: The DECTRIS team, comprising engineers and scientists, is ready to assist users in obtaining the maximum from their setup.
