Abstract
A binocular telescope with internal focusing and two cylindrical barrel tubes, each fastened to a bridge and accommodating an objective lens, a focusing lens, a prism system for image inversion and an eyepiece. The prism system is configured so that the optical axis of the eyepieces is offset relative to the optical axis of the objective lenses. The bridge is provided with two cylindrical apertures in which the barrel tubes are mounted parallel to one another, each rotatable about the optical axis of its objective. Each barrel tube comprises a rotary sleeve, an objective tube and an eyepiece tube. The bridge is one piece and has a small length compared to the barrel tube length. The rotary sleeves are inserted into the apertures and the objective tubes and eyepiece tubes are connected to the rotary sleeves such that they lie rotatable on the upper and lower sides of the bridge.
