Binocular tube and stereoscopic optical observation apparatus

Abstract

A binocular tube is equipped with an eyepiece viewer having a first eyepiece and a second eyepiece; a tilting mechanism for tilting the eyepiece viewer about a tilt axis; a pupillary distance adjusting device for adjusting the pupillary distance between the first eyepiece and the second eyepiece of the eyepiece viewer; and at least one manually operable actuation element coupled or couplable to the pupillary distance adjusting device and which makes it possible to set the pupillary distance by an actuation action. The binocular tube is equipped with a switching device enabling switching from a coupling of the manually operable actuation element to the pupillary distance adjusting device to a coupling of the manual actuation element to the tilting mechanism of the eyepiece viewer, such that the actuation action makes it possible to set the tilting of the eyepiece viewer instead of setting the pupillary distance.
