CsI(Tl) scintillation detector with reflective TiO2 coating. Crystal size 26*22*8 mm = 4.576 cm3, TiO2 coating thickness 0.5 mm, so overall detector size is 27*23*9 mm.
CsI(Tl) is one of the brightest scintillators for it's price. Can be coupled with photodiode or SiPM readout. Actual crystal can slightly differ from photos.
