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.
Current sizes range from 0.5 mm to 3 mm round cross-sections and are available in canes, spools, ribbons, and arrays. Custom sizes and designs available upon request. 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.
Features/Benefits
Flexibility to conform to the surface shape, yielding geometries superior to those of other types of detectors. Examples are detectors for monitoring pipes or barrels.
