BCF-XL Series
Starting in 2023, Luxium Solutions introduced the BCF-XL series of scintillating and wavelength shifting fibers with improved, market-leading attenuation length for optimal, reliable performance for a variety of different applications. Properties of our BCF-XL fiber formulations can be found in the table below.
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 are 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.
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.

Frequently Asked Questions
Are fibers sensitive to Neutrons?
All scintillating fibers are sensitive to fast neutrons through proton recoil.
How is fiber light output defined?
We define the light output as # of photons per MeV for minimum ionizing Particle, which is approximately 8000 for BCF-12. The more densely ionizing particles emits less light than per unit energy.
What is the fiber spool size?
Fiber is wound on a spool that measures 30" (762mm) outer diameter x 27.4" (698.5mm) core x 2.25" (57mm) with 1" (50.8mm) center hole. It will fit 1000 meters of 1mm fiber.
What is the lower temperature limit of Scintillating Fiber?
The lower limit on operating temperature has not been set, but research experiments have used fiber in temperatures down to about 4 degrees K. Fiber will lose their flexibility at low temperatures.
What is the typical bend radius of a scintillating fiber
The typical bend radius is 30-40 times the diameter of the fiber.
