CdWO4 Scintillation Crystal
Cadmium Tungstate (CdWO4) is a premium, high-density scintillator distinguished by its high atomic number, exceptional radiation resistance, and strictly zero radioactive background. Delivering a stable light output of 12-15 photons/keV with a peak emission at 475nm, it achieves 30-50% of the light yield of NaI(Tl) while maintaining ultra-reliable, interference-free performance.The critical combination of robust light output and exceptionally low afterglow makes CdWO4 the ultimate material for seamless coupling with silicon photodiodes (PDs). This specific synergy is highly sought after by engineers designing next-generation medical and industrial Computed Tomography (CT) scanners, guaranteeing razor-sharp, high-resolution imaging without trailing artifacts.ATR Crystal precision-manufactures standalone CdWO4 crystals alongside fully customized linear and 2-D CdWO4 arrays. We tailor every configuration to your exact specifications, maximizing detection efficiency for your most rigorous scanning systems.
