Description:
A rugged polymethyl methacrylate fibre with a polymer cladding and black protective sheath which may be bent and handled in the same way as insulated wires without damage. Ideal for use in equipment to provide several light sources possibly in confined spaces from a single lamp some distance away.The fibre as supplied has a roughly cut end and this should be cleanly sliced off using a razor blade or a very sharp knife. Light transmission can be increased by typically 33% by polishing the ends of the fibre after cutting.
