Abstract
1373234 Optical apparatus RICHARD WOLF GmbH 18 Oct 1971 [20 Oct 1970] 48280/71 Heading G2J [Also in Division A5] An optical system for investigating body cavities comprises an eye-piece 4, a fibre optic bundle 2 and an objective 1, which is a glass rod wherein the refractive index varies parabolically in cross-section. The bundle may be enclosed in sheath 5, and the fibre optic bundle may be flexible, or rigid e.g. formed of fused fibres.
