Electro Optical Components, Inc. Scintillator Materials Eu:CaF2 Crystal

CaF2:Eu is a scintillation material that used for detecting hundreds keV low energy gamma rays and charged particles. Because of its low effective atomic number, limit it in application of high energy gamma-ray spectrometer, but makes it an ideal material for the detection of beta rays. Its refractive index is at 1.47, which is very close to most PMT windows’ and optical coupling modules’ refractive index, so it can obtain high light collection efficiency.
