Abstract
A leached fiberscope formed of a multiplicity of optical fibers each surrounded by a stray light absorber adjacent opposite ends of the fiberscope. This light absorber is formed by adding a light-absorbing constituent to leachable overcladdings initially provided on the optical fibers which are retained adjacent opposite ends of the fiberscope as the absorber and removed from intermediate portions of the length of the fiberscope to render it flexible.
