Lead Fluoride (PbF<sub>2</sub>) Single Crystal,  MSE Supplies LLC

Lead Fluoride (PbF2) Single Crystal

  • $ 7450


Lead Fluoride - PbF₂ is a highly effective gamma-ray absorber as a result of its high density, fast decay time, and a high radiation hardness.  These scintillator crystals are useful in diverse applications such as Positron Emission Tomography (PET) and specialty applications in high energy, nuclear, space and medical physics. PbF2 crystal substrates are available for purchase. Customized PbF2 crystals can be supplied by MSE Supplies based on customer's requirements.
