1. An adjustable microscope tube for a microscope, said microscope tube comprising, in order, along its beam path starting from an entrance to the microscope tube:
an optical system positioned to receive light from a microscope objective, which images a first intermediate image to infinity, wherein the first intermediate image is a real image;
at least one deflecting element, following the optical system, which folds the parallel beam path; and
collecting optics, arranged following the deflecting clement in the beam path, imaging the first intermediate image imaged to infinity onto a second intermediate image,
wherein the length of at least one portion of the folded, parallel beam path can be changed by displacement of the deflecting element relative to the optical system.
