CsI(Tl) Array

Advantage

1.Wavelength 550nm for PD

2.Excellence performance for afterglow and brightness in low energy x ray

3.Low cost

Description
  • CsI(Tl) Cesium Iodine doping thallium is the most typical alkali halide scintillation crystal which wavelength is 550nm, It’s best matchable for PD, SiPM etc. CsI(Tl) has high density, High Z, No cleavage plane, excellent detection effiency, it’s widely used in high energy physics, Nuclear detector, Space detection, security inspection,SPECT and container checking etc.
