L(Y)SO scintillator crystal, lutetium (-yttrium ) oxyorthosilicate, is a new generation artificially synthesize scintillation crystal material. It has the advantages of high density, fast decay time, high light output, high energy resolution, etc. The gamma-ray detector made of this crystal has a very broad application prospect in nuclear medical imaging, high energy physics, nuclear physics and other fields. It is the core detection component of the new generation positron emission tomography (PET).

We can produce and manufacture the arrays based on customers’ different design options in terms of pixel size, the number of pixels, pixels separator materials(reflective and/or radiation barrier) and crystal surface finishes. Our 2D arrays are typically used with pixilated photodiodes, position sensitive photo multiplier tubes(PSPMT) and silicon photomultipliers(SiPM). We offer a variety of design options and reflector materials to optimize array performance for the special application. Tianle Phonics manufacturing process ensures high light output as well as excellent pixel to pixel uniformity with minimal crosstalk.
