ABSTRACT:
A changing device (60) for an optical examination device, for example a microscope, comprising two beam paths (61.1, 61.2) for a first optical image, and a changing optics (21) which is rotatably arranged in the changing device and is, for example, a Galilei magnification changer having at least two, here three pairs of beam paths (35.1, 35.2and45.1, 45.2and55.1, 55.2, respectively) which can optionally be switched into the beam paths (61.1, 61.2) of the changing device by rotating the changing optics. In accordance with the invention, the changing optics (21) comprises for each pair of beam paths at least one, here two additional beam paths (36.1, 36.2and46.2, 46.2and56.1, 56.2, respectively), assigned to the respective pair of beam paths, and the changing device (60) likewise comprises at least one, here likewise two additional beam paths (61.3, 61.4). The changing optics (21) is designed in such a way that it is simultaneously possible during rotation of the changing optics (21) for the beam paths (35.1, 35.2and45.1, 45.2and55.1, 55.2, respectively) of one pair to be inserted into the beam paths (61.1, 61.2) or removed therefrom, and for the additional beam paths (36.1, 36.2and46.2, 46.2and56.1, 56.2, respectively) assigned to the respective pair to be inserted into the additional beam paths (61.3, 61.4) of the changing optics or removed therefrom.
