SPEAR CZT-based radiation detector

Everything you need in a CZT- based gamma radiation detector for your laboratory

CZT-based gamma radiation and x-ray detector

The SPEAR detector is a CZT-based gamma radiation and x-ray detector perfect for immediate use or as the gamma radiation and x-ray detector component in your own radiation detector. Being CZT-based the SPEAR (Single Point Extended Area Radiation) can operate at room temperature while still offering high sensitivity. The SPEAR detector is a complete probe, comprising a 5x5x5mm3 CZT detector crystal and low noise hybrid preamplifier in a housing measuring only 13mm diameter x 84mm in length. The probe is supplied complete with a 2 metre long connecting input/output cable, allowing the unit to be used immediately.

Designed for nuclear spectroscopy in a nuclear lab and with NIM bin electronics and your own spectroscopy software.

It is a low-cost unit, perfect for high count environments.
