Scintillation Crystals

Scintillation Crystals

Hilger Crystals is a leading producer of an extensive range of scintillation crystal materials for X-ray, gamma-ray and neutron detection and X-ray imaging. Applications include medical, industrial and security X-ray imaging. Scintillation crystals include Caesium Iodide-CsI(Tl), Sodium Iodide-NaI, Lutetium Yttrium Silicate-LYSO, Bismuth Germanate-BGO, etc.

Scintillation crystals are used in detectors to convert X-rays or Gamma rays into light pulses that are subsequently detected by either a photomultiplier tube (PMT) or a photodiode (SiPM).

Pixelated crystal X-ray imaging arrays can be either linear or two dimensional with individual pixels as small as 0.5mm depending on material and thickness.
