CsI(Tl) Scintillators

the advantages of high density, high Gamma-ray stopping power, good energy resolution, high light output, high detection efficiency for gamma-ray and X-ray. It has no cleavage plane and good processibility, can be made into various shapes. In addition, because of its emission in the long-wavelength part of the spectrum (>500nm), it is well-suited for photodiode readout. CsI(Tl) crystal is widely used in high energy physics, nuclear physics, space physics, security inspection (luggage & container), industrial level gauge and so on.


OST Photonics ia able to supply the CsI(Tl) crystals, CsI(Tl) scintillation screen, CsI(Tl) linear or 2-D arrays upon request. In addition, we can also supply low afterglow type CsI(Tl) crystals with afterglow of 0.05~0.39%@20ms. Low afterglow type CsI(Tl) crystal not only retains the advantage of high light output of standard type CsI(Tl) crystal, but also significantly inhibits the afterglow. It effectively improves the problem of afterglow trailing in the scanning radiation imaging system and improves the imaging quality. It is very suitable for the imaging system which requires high imaging quality and fast scanning.
