- Lutetium Fine Silicate Scintillation Crystals
LFS (Lutetium Fine Silicate) series of scintillation crystals are distinguished by their combined high light yields and ultra-fast decay times.
The LFS crystals developed at Zecotek (BC, Canada), covers a wide range of emission wavelengths which can be tailored to match the spectral
sensitivity of various PMT detectors and SiPM based avalanche photo detector arrays.
The LFS Superlative light yields (80-85% – NaI scale) and decay constants (<33ns) set them apart from other industry contenders. The superior radiation hardness of our LFS crystals also make it ideally suited for many types of high-energy physics experiments and other applications associated with high levels of ionizing radiation. These performance advantages enable faster, higher resolution operation of medical and industrial imaging devices – including PET, PET-CT and Gamma cameras.
