The fiber is made with a core of polystyrene surrounded by a clear acrylic cladding. Special fluorescent dyes are added to the core. The fluorescent die absorbs photons of a shorter wavelength, and emits them in a longer wavelength (the extra energy shows up as heat). Light which is within the fiber’s capture angle is guided down the fiber to the end for viewing. Popular applications include scientific, targeting sights, modeling, and artistic.
