X-ray scalable linear array

Scalable CZT linear array for baggage inspection, CT or building prototypes for medical applications

CZT-based detector for real-time operation

The EV3500 is a fully integrated photon counting energy discriminating cadmium zinc telluride (CZT) detector with an onboard microcontroller and FPGA allowing true real-time operation.

The solid-state CZT detector technology provides superior efficiency and energy discrimination capabilities versus conventional Scintillation-based detectors.

CZT based detectors are rapidly becoming the technology of choice in many of today’s most advanced medical, industrial and security applications.
