DECTRIS QUADRO Hybrid-Pixel Electron Detector

QUADRO is a hybrid-pixel, radiation-hard electron detector from DECTRIS that enables users to concentrate on their sample rather than the camera.

QUADROis the first direct electron detector to be launched by DECTRIS. It is based on hybrid-pixel technology and is fitted with DECTRIS’ signature instant retrigger, noise-free acquisition, and continuous readout.

The DECTRIS QUADRO detector can count every single electron even at a high count rate (up to 10 million el/s/pix), and guarantees a more precise data collection.

Owing to QUADRO’s remarkably high dynamic range, the experimental setup will not require a beam stopper. This will allow users to acquire continuous diffraction patterns.

This feature, along with the sensitivity and speed of the QUADRO detector, transforms methods such aselectron imaging, strain imaging, micro-electron diffraction (microED), and ptychography.

Efficient: QUADRO detector’s rapid readout chip, integrated with its silicon sensor material, offers suitable Detective Quantum Efficiency (DQE), even if energies are low.

Easy: The QUADRO detector matches well with SerialEM. Its application programming interface (API) allows direct integration into any microscopy application platform.

Radiation-hard: The QUADRO detector does not need a beam stopper. Thiswill enable users to gather all data without intrusion.
