QUARDO Detector
Description
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.
