Abstract
The technology generally relates to a binocular having two tubes, which are connected to one another by means of a hinged bridge pivotable about a hinge axis for adjusting the interpupillary distance. Within each of the two tubes a beam path is formed with a first optical axis of an objective lens, with a second optical axis of an eyepiece and with a prism erecting system, characterized in that the first optical axis of the objective lens and the second optical axis of the eyepiece are offset parallel to each other by a distance.

A binocular having two tubes, which are connected to one another by means of a hinged bridge pivotable about a hinge axis for adjusting the interpupillary distance, wherein in the two tubes, in each case, a beam path is formed by an objective lens, an eyepiece and a prism erecting system, wherein a first optical axis of the objective lens and a second optical axis of the eyepiece are offset parallel to each other by a distance so that these axes do not coincide, characterized in that the first optical axis of the objective lens and the second optical axis of the eyepiece lie in a common first plane with the hinge axis of the hinged bridge, wherein said prism erecting system comprises a Schmidt-Pechan prism system or an Abbe-Koenig prism, and wherein a tip of a roof section, consisting of two faces meeting at a 90° angle, of the prism erecting system is arranged facing outwards relative to the hinge axis.
