Thallium doped cesium iodide, CsI(Tl), Its light output is 85% of that in NaI(Tl). Its emission spectrum has a broad band at 350-700nm and a peak at 550nm. Its emission spectrum can match well with SPD so that the read out system can be simplified.  

Types：Blank and Aluminum encapsulation
Max blank size：40mmx80mmx200mm
Shapes: cylinder, rectangular solid, disk
The thinnest thickness will be 0.2mm
