Crystal CsI(Tl) Scintillator PD Detector
Well-suited for photodiode readout crystal CsI(Tl) scintillator PD detector
CsI(Tl) scintillator has a light output of 54 photons/keV and is one of the brightest scintillators known.
The maximum of the broad emission is situated at 550nm and the emission is, therefore, not well matched to a bialkali photocathode photomultiplier tube. However, since most of its emission in the long-wavelength part of the spectrum (>500nm), it is well-suited for photodiode readout.
