Scintillator arrays integrated with pixelated photodiodes, position-sensitive photomultiplier tubes (PSPMT) and silicon photomultipliers (SiPM) are the core components of many radiation scanning and imaging instruments, they are widely used in Positron Emission Tomography (PET), CT Imaging, gamma-ray camera, line Scanning, industrial imaging, baggage scanners, cargo inspection and digital radiography. Different applications have different requirements for scintillator arrays, so choosing the right scintillation crystal material is very important.
OST Photonics provides various of scintillator arrays, including LYSO(Ce) array, CsI(Tl) array, BGO array, CdWO4 array, GAGG(Ce) array, LaBr3(Ce) array, YSO(Ce) array, LSO(Ce) array and so on. We offer a variety of design options and reflector materials to optimize array performance for your application. Our manufacturing process can ensure the highest light output, excellent pixel-to-pixel uniformity and minimal crosstalk.

Linear arrays (1-D array) are usually used with photodiodes and used quite often in security type applications, most common are baggage scanners, cargo inspection, and other non-destructive testing applications. The following linear array drawing is for your reference:
Two-dimensional arrays (2-D array) are usually used with pixelated photodiodes, position-sensitive photomultiplier tubes (PSPMT) and silicon photomultipliers (SiPM) and most common use is in medical imaging scanners (PET, SPECT, CT), and non-destructive testing applications. The following two-dimensional array drawing is for your reference:
