ABSTRACT:
An endoscopic telescope has a system tube in which spacer tubes are alternatingly stacked with rod lenses each having an external diameter smaller than the inside diameter of the system tube and which have convex end faces supported against the axial ends of the spacer tubes. An end of at least one of the spacer tubes protrudes axially at an angle and at a rotational position so that it abuts the adjacent convex surface of a rod lens, thereby tilting the rod lens relative to the system tube axis. The spacer tubes and the rod lenses are mounted spring loaded between end holding devices in the system tube.
