Side-hole type NaI(Tl) Scinitllators
The side-hole type NaI(Tl) scintillator is a detector with a side-hole passing vertically through the axis of the cylindrical NaI(Tl) crystal. It is usually encapsulated in aluminum housing. The measured specimen is passed through the side hole, and light output can be obtained from an optical window mounted on one or both sides of the end surfaces. 
Hangzhou Shalom EO offers the customerized side-hole type NaI(Tl) scintillators upon customer's request.
