HEXITEC
The HEXITEC detector measures the energy and position of every incident photon in the 4-200 keV range. Each one of the 80×80 pixels provides a full energy spectrum with an average energy resolution of 800 eV FWHM at 60 keV.
HEXITEC is a self-contained module that requires only a mains power supply and connection to a PC. It is supplied with a user friendly GUI to operate and calibrate the detector. Industry standard Gig-E Vision APIs can be supplied for users to integrate into their own systems.
