Premium LaBr3(Ce) Scintillators: Ultimate Energy Resolution
Cerium-doped Lanthanum Bromide (LaBr3:Ce) represents a massive leap forward in advanced radiation detection. Delivering significantly higher light output and vastly superior energy resolution compared to traditional NaI(Tl) crystals, it sets a new industry benchmark for precision. Characterized by outstanding energy linearity and an ultra-short scintillation decay time, this material guarantees absolute accuracy under both gamma-ray and X-ray excitation.
ATR Crystal engineers fully customized solutions for your most demanding applications. We supply robust encapsulated LaBr3(Ce) scintillators, specialized high-temperature variants for deep oil logging, and precision-cut pixellated LaBr3(Ce) arrays. For next-generation compact systems, we offer complete scintillation detector assemblies seamlessly integrated with SiPMs. From critical nuclide identification and environmental monitoring to nuclear medicine and dual-use security inspection, our LaBr3(Ce) technology empowers the world’s most sensitive detection equipment.
