ABSTRACT:
A generally flexible fiber-optic light guide comprising a multifilament bundle of coated fibers in a sheath and having at least one permanently bent portion defining a rigid curve, the bent portion being arranged within an end piece or socket of the light guide; the coated fibers within the bent portion being closely packed and embedded in a solid material capable of serving as a lubricant when in an uncured state. The permanently bent portion is produced by arranging the coated fiber closely packed in a straight tube made of a ductile material, filling the tube with an agent capable of serving as a lubricating agent when in an uncured state, bending said tube with the fibers and the lubricating agent and curing the lubricating agent so as to form a solid matrix or bedding for the fibers in the bent portion.
