Our story

Quantum Detectors was founded in 2007, a technology spin-out from the Science & Technology Facilities Council (STFC) and Diamond Light Source (DLS), the UK’s synchrotron radiation facility. Our core mission was a clear one. Make our cutting-edge technology accessible to the global science community. And that’s what we’ve done.

The company today is a market-leading provider of advanced direct electron detectors and readout solutions employed in TEM and synchrotron radiation facilities throughout the world. Serving scientific and commercial research sectors, we have gained a reputation for customer service and support with our lifetime product care, continuous product improvement and bespoke solution capability.

Quantum Detectors is now recognised as being at the forefront of 4D STEM analysis, having the largest installed base of DEDs supporting all major TEM brands, including Hitachi, JEOL and Thermo Fisher Scientific. And with several hundred installations operational in the field, our readout systems are leading the way in accessing high-quality beamline data.

Our journey to bring new technology to you


Quantum Detectors was founded with its first employee. March, 2007

The company was provided with initial funding and tasked with commercialising technology developed at the SRS synchrotron at Daresbury Laboratory.


First Xspress 3 commercial units installed, 2012

Diamond Light Source were the first recipients of a commercial Xspress 3 system from QD, and went on to put them on over half of their beamlines since.

Xspress 3 mini developed, 2015

In response to customer requests for a smaller more nimble digital pulse processor, we redesigned the Xspress platform to create Xspress 3 mini. The hardware is now portable between detectors and the software redesigned to allow a user friendly recalibration in just a few minutes.

1st MerlinEM installation, 2016

A collaboration between QD and the University of Glasgow, the first MerlinEM direct electron detector for electron microscopy use was installed at the University of Antwerp in the group of Prof Jo Verbeeck.

Partners who help our mission

Quantum Detectors is partnered with STFC and DLS in the on-going development of cutting-edge DED and readout system products. At the same time, we collaborate closely with larger scale facilities like the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, and academic institutions like the University of Glasgow, Scotland.  Such strategic relationships ensure we remain at the forefront of new industry thinking.

We’ve had a Merlin detector installed on our JEOL GrandArm 300 since 2016, and it is a crucial component of our user capability at ePSIC. The rapid readout, zero noise, and high dynamic range of the camera have really opened up the possibilities for 4D STEM and other applications, particularly under low dose conditions. Quantum Detectors have been great to work with as they are very receptive and responsive to our feedback, and have continued to develop the detector and software to better suit the scientific community. We have now installed a further MerlinEM 4R camera on our new JEOL microscope ‘Ruska’ at the Rosalind Franklin Institute, for use in ptychography of biological samples
