The invention is directed to a telescope-type stereo microscope comprising a microscope objective, a tube lens system in each of the two stereoscopic imaging beam paths downstream of the microscope objective, a microscope viewer, and a device for adjusting the focus position by changing the distance z between the microscope objective and an object to be observed. A microscope of the type described above is constructed in such a way that the distances between the object and the microscope viewer and the distance of at least one lens of the tube lens system from the microscope objective or from the microscope viewer are constant when changing the distance z between the microscope objective and the object to be observed, and a real image is always formed at the same location of the microscope viewer. In contrast to the prior art, it is no longer necessary to move the entire mass of the microscope superstructure for focus adjustment. Therefore, the guides and drives required for the focusing movement can be designed so as to save costs and space.
