LYSO(Ce) Array
LYSO(Ce) (Cerium-doped Lutetium Yttrium Orthosilicate) crystals feature high density, high light yield, fast decay time, and superior energy resolution. Gamma-ray detectors utilizing LYSO(Ce) crystals hold broad application prospects in fields such as nuclear medicine imaging, high-energy physics, and nuclear physics. They serve as the core detection components for next-generation Positron Emission Tomography (PET).At Atr Crystal, we manufacture custom LYSO(Ce) arrays tailored to your specific design requirements, including pixel size, pixel count, reflector materials, and crystal surface finishes. Our 2D LYSO(Ce) arrays are fully compatible with pixelated photodiodes, position-sensitive photomultiplier tubes (PSPMTs), and silicon photomultipliers (SiPMs). We provide a diverse range of design configurations and reflector options to optimize array performance for your specialized applications. Our advanced manufacturing process ensures high light output, excellent pixel-to-pixel uniformity, and minimal optical crosstalk. Furthermore, offset LYSO(Ce) arrays (multilayer configurations) are also available upon request.
