Abstract
The invention concerns an image-inverting system for a sighting telescope, where the image-inverting system has at least two mutually displaceable lenses in a tube of the image-inverting system parallel to an optical axis of the image-inverting system, where displacement of the at least two displaceable lenses modifies the reproduction scale at which an image projected onto a first image plane of the image-inverting system is shown on a second image plane of the image-inverting system, where the at least two displaceable lenses are arranged in any position between the first and the second image plane, where a surface of the inside of a tube facing the optical axis having at least one absorption area with absorption zones for absorbing incident light and with sliding surfaces located between neighboring absorption zones for bearings of the at least two displaceable lenses, where the total area of the sliding surfaces is smaller than the total area of the absorption zones, where the at least one sliding surface is arranged at a different distance from the optical axis than the at least one absorption zone.
