ABSTRACT:
An endoscope is disclosed for determining the size of an object in a cavity, for example in a human or animal body or in a machine. The endoscope comprises an optical system for viewing the object laterally from its distal end. The transmission system has an image plane, visible through an eyepiece, on which a measuring scale is provided. By viewing a selected part of the object simultaneously or successively from two different angles, with a predetermined distance between their vertices, at a constant lateral distance from the endoscope, images of the object can be seen at two different positions on the measuring scale, from which the size of the object can be calculated.
