Abstract:
1. A tube for an optical observation device, having a viewing level that is linearly variable in length and/or height, wherein the tube has an optical light path, in which at least two optical elements are disposed, wherein at least two optical elements are disposed so that they can move independently of one another in the optical light path, wherein the tube has a base part, in which as an optical element a deflecting element is disposed so that it can rotate around a first axis of rotation, wherein the tube has an eyepiece support which can swing relative to the base part and in which as an optical element a deflecting element is disposed so that it can rotate around a second axis of rotation, wherein an intermediate support is provided which is joined with the base part and with the eyepiece support so that the eyepiece support can swing relative to the base part, via the intermediate support, wherein the intermediate support is joined with the base part via a rotating joint and with the eyepiece support via a rotating joint, wherein the deflecting element of the base part is coupled with the rotating joint which joins the base part and the intermediate support, and wherein the deflecting element of the eyepiece support is coupled with the rotating joint which joins the eyepiece support and the intermediate support, hereby characterized, that the deflecting element of the base part is connected to a coupling element, said coupling element cooperating with a driver element being connected to the base part, and with a driver element being connected to the intermediate support, and that the deflecting element of the eyepiece support is connected to a coupling element, said coupling element cooperating with a driver element being connected to the eyepiece support, and with a driver element being connected to the intermediate support.
