Project Description

AXIS-SXR: 4 Mpix Soft X-ray sCMOS camera

AXIS-SXR is a new soft x-ray sCMOS camera for measurements from 20 eV to 2 keV. This camera was developed and characterized by the detector group and SEXTANTS team of SOLEIL Synchrotron (France). It is based on a new backside illuminated scientific CMOS (BSI-sCMOS) which is able to acquire low noise 4 Mpix images with a frame rate up to 30 Hz through its optical link.

It is built to sit entirely under vacuum. For a fraction of the price, it is more efficient than the high-end x-ray cameras presently on the market.

We now offer a choice of 3 different sensors to suit your needs.

The mechanics have been designed to allow the user to easily change the detector in case of an experiment mishap or if the experiment requires another type of sensor.

As for software, a generic control application is provided. A SDK and a Tango device are also available.

We also propose a flanged version so it can be mounted on a vacuum chamber or spectrometer.
