CdWO4 Scintillators

CdWO4 Cadmium tungstate crystal is a high density, high atomic number scintillator with a relatively high light yield. The emission maximum is at 475nm and the total light output is 12 to 15 photons/keV. The light yield relative to NaI(Tl) on a bialkali PMT is 30 to 50%. In addition, it also has the advantages of strong radiation resistance and no radioactive background. The high light output and low afterglow make it ideal for use with silicon photodiodes in detectors for medical and industrial Computed Tomography (CT) scanners.


OST Photonics is able to supply CdWO4 crystals and CdWO4 linear or 2-D array upon your requests.
