Scintillating Fiber

A variety of plastic scintillating, wavelength-shifting and light-transmitting fibers are produced for research and industry.  Scintillating fibers consist of a polystyrene-based core and a PMMA cladding. The scintillating core contains a combination of fluorescent dopants selected to produce the desired scintillation, optical and radiation-resistance characteristics. Multi-clad fibers have a second layer of cladding that has an even lower refractive index and, thus, permits total internal reflection at a second boundary. The additional photons guided by multi-clad fibers increase the output signal up to 60% over conventional single-clad fibers.

Current sizes range from 0.25 mm to 5 mm square or round cross-sections and available in canes, spools, ribbons, and arrays. Fibers > 2mm are available only in cane form to prevent the fiber from retaining the shape of the spool.

Scintillating fibers are well-suited for such applications as Industrial gauging, Calorimeters, Real-time imaging systems.
