Abstract
Abstract An elongated metal channel having a U-shaped cross-section has a cover and end caps secured thereto forming a housing. Along one wall of the housing are drilled longitudinally spaced holes. In some of the holes (which may have different orientations) are fixed metal collars having secured therein one end of a bundle of optical fibers. The fiber ends are secured by an adhesive which has been cured, after which the ends are polished. The fiber bundles are led through the housing to an opening (which may be in the cover) where a flexible sleeve has one end mounted. The fibers are threaded through the flexible sleeve and secured in a tip at the other end of the sleeve. The fibers in the tip are secured therein by an epoxy and polished. In some cases the metal collars with the fiber bundle are positioned at the end of a gooseneck with a lens mounted adjacent to the tip. The method by which the fibers are mounted in the collars is described.
