Abstract

An adjustable microscope tube for a microscope includes, in this order, along its beam path coming from an entrance to the microscope tube: an optical system, which images a first intermediate image to infinity; at least one deflecting element, which folds the parallel beam path following the optical system, and collecting optics, arranged following the deflecting element in the beam path, for imaging the first intermediate image, which has been 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.
