Based on hybrid-pixel technology, QUADRO is the first direct electron detector to be released by DECTRIS. It incorporates our signature instant retrigger, continuous readout, and noise-free acquisition. Even at high count rate (up to 10 million el/s/pix), DECTRIS QUADRO® detector is able to count every single electron, and thus assures more accurate data collection.

Thanks to QUADRO’s exceptionally high dynamic range, your experimental setup will no longer require a beam stopper, and this will allow you to obtain uninterrupted diffraction patterns. This characteristic, combined with QUADRO detector’s speed and sensitivity, make it a game-changer for techniques such as Micro-Electron Diffraction (microED), electron imaging, strain imaging, and ptychography. 

  • Efficient: QUADRO detector’s fast readout chip, combined with its silicon sensor material, provides the ideal Detective Quantum Efficiency (DQE)—even at low energies.
  • Radiation-hard: QUADRO detector doesn’t require a beam stopper, and this will allow you to collect all data without interference.
  • Easy: QUADRO detector is compatible with SerialEM. Its Application Programming Interface (API) enables straightforward integration into any microscopy application suite.
