PIN Module for Radiation Detection

This radiation detection module from First Sensor combines a 100 mm2 photodiode with an 8 mm CsI:Tl scintillator. The module measures only 17 by 16 by 19 mm and detects gamma radiation in the energy range of 150 to 1500 keV.

For 20 years now, First Sensor has developed and produced a wide variety of photodiodes with high sensitivity, fast speed and low dark currents. Our development expertise, proprietary laboratories, and clean rooms enable us to make any kind of client-specific modification. Our detectors are thus optimized for ultraviolet, visible, and infrared light as well as ionizing radiation. First Sensor radiation detectors can be equipped with or without scintillators, according to their application.
