Light transmission device.

摘要

This coupling means comprises a sleeve (50) containing a bore (52) in which is located a bundle of optical fibers (16), at least some of which are of compression-deformable material. The input ends of the fibers, which receive light from a light source, are located in a predetermined plane (67). The bore tapers from a relatively large diameter at a location in a second plane spaced from said predetermined plane to a relatively small diameter at said predetermined plane. The tapered bore is of such a size that the optical fibers therein are laterally compressed and the compression-deformable fibers are so deformed in transverse cross-section relative to their normal cross-sections that the fibers more completely fill the bore in its relatively small diameter region than in said second plane.
