CZT Strip Detector | Prosun Semiconductor

A CZT (Cadmium Zinc Telluride) strip detector is a type of radiation sensor that uses a CZT crystal segmented into narrow strips to detect X-rays or gamma rays with high spatial and energy resolution. The strip configuration allows for precise position-sensitive measurements, enabling imaging and spectroscopy applications in fields such as medical diagnostics, industrial inspection, and security screening, while operating efficiently at room temperature.
