ABSTRACT:
An endoscope tube having at least one image inversion system consisting of two rod lenses, in which the first rod ends, pointing to an intermediate image plane, have a marginal cylinder, which is mounted in the endoscope tube, in which the second rod ends, which lie symmetrical to an aperture plane, have a diameter that is smaller than the inner diameter of the endoscope tube, so that the end surfaces associated with the first rod lenses are convex in configuration, the end surfaces associated with the second rod ends can be cemented together with a lens element, and a distance holder that defines the aperture area is inserted between the two rod lenses, is characterized in that the rod diameter in each case continually decreases from the marginal cylinder toward the second rod end.
