CsI(Tl) Array

CsI(Tl) Thallium-activated Cesium Iodide crystal is one of the brightest scintillator materials, it has 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) crystals can be manufactured into linear and 2-D arrays, CsI(Tl) arrays has been widely used in X-ray security inspection systems, non-destructive testing, food inspection and other applications.


OST photonics is able t o supply CsI(Tl) linear arrays and CsI(Tl) 2-D arrays according to our customers' requirements. We usually use titanium dioxide (TiO2) as the reflector between each single pixel (element). The CsI(Tl) arrays produced by us has high resolution and high sensitivity characteristics, which can achieve excellent imaging quality. In addition, we can also supply low afterglow type CsI(Tl) crystal materials with afterglow of 0.05~0.39%@20ms. Low afterglow CsI(Tl) crystal not only retains the advantage of high light output of standard 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.
