Plastic Scintillators


Eljen Technology's plastic scintillators are based on a plastic matrix of polyvinyltoluene and fluors necessary to give each plastic scintillator its unique properties. Our plastic scintillators are available in a variety of different geometries, including cast sheets, blocks, rods, cylinders, thin films, and annuli. Custom sizes and geometries are available for most of these products. All plastic scintillators are cut to customer specified dimensions and machined to ensure the best optical properties on all surfaces.

Custom plastic scintillator detector assemblies are also available. Such assemblies generally include acrylic light-guides, light-tight wrapping, and one or more photomultiplier tube assemblies (includes photomultiplier tube, voltage divider, Mu-shielding and light-tight housing). Please contact us regarding your specific requirements.
