QUADRO

The new DECTRIS QUADRO detector is designed to deliver outstanding performances to materials science Transmission Electron Microscopy (TEM) without any compromise on accuracy, speed, or sensitivity, delivering 24-bit high dynamic range and up to 18‘000 frames/sec readout, no binning, no gimmicks!

The DECTRIS QUADRO is powered by our new EIGER2 ASIC (Application Specific Integrated Circuit), entirely designed by DECTRIS and featuring everything which made the success of our detectors for the most demanding X-ray applications: hybrid pixel technology, instant retrigger, continuous readout and noise-free acquisition.

The QUADRO is a direct electron detector based on hybrid pixel technology where the best readout chip is matched with the most suitable sensor material to provide the optimized sensitivity (DQE) for your application. Dedicated in-pixel electronics allow for single electron counting even at very high count-rates, up to 10 million electrons/pixel/second. The sensor material can be adapted to the energy range of your application.

The detector is compatible with the SerialEM program and a variety of transmission electron microscopes. QUADRO is fully integrated into NanoMegas TopSpin and Strain applications.
