Abstract: A digital microscope system, having one or several objectives, a tube lens system, a digital image recording device, a stand, a holder for a specimen and an illuminating apparatus, and optionally at least one magnification changer. One or several objectives, the tube lens system, the digital image recording device and the illuminating apparatus are integrated into a compact optical assembly, and the optical assembly is joinable to the stand in several versions that differ with regard to the spatial position and orientation of the optical assembly relative to the stand and to the specimen. The spatial position and orientation of the optical assembly relative to the stand and to the specimen may correspond, in a first version of the joining, to an upright microscope configuration and, in a second version of the joining, to an inverted microscope configuration.

This changing device is arranged at a holder in the telecentric part of the microscope beam path and is outfitted with a quantity of optical components influencing the beam path. The arrangement is mounted so as to be rotatable around an axis of rotation which is situated in the holder and which intersects the optical axis of the microscope beam path. This axis of rotation defines, with the optical axis, a plane extending substantially perpendicular to the front wall of the microscope stand. The part of the changing device which is not located in the microscope beam path and which lies diametrically opposite to the part of the changing device that is located in the beam path is arranged so as to be directed toward the microscope stand and is adjacent to the front wall of the microscope stand.

The required optical elements are accommodated in components that can be mechanically separated from one another and variously combined. The optical system is calculated in such a way that an upright microscope with vertical illumination or transmitted illumination or an inverted microscope with vertical illumination or transmitted illumination results when the components are combined in the required manner by interfaces provided for this purpose.

In the microscope, a supporting cell is provided which is optimized with respect to material and rigidity and is connected to the stand rigidly but so as to be exchangeable. First assemblies for receiving, holding and adjusting the objective and second assemblies for positioning the object or specimen relative to the objective are arranged at the supporting cell. The first assemblies are designed as an objective changer device and/or as an objective focusing device, and the second assemblies comprise a stage support, a stage guide, and a stage.

Abstract: A method for generating a stereoscopic image of an object includes providing a microscope arrangement defining an imaging beam path coming from the object. The microscope arrangement includes an objective mounted in the beam path to define an intermediate image plane. A reflective element is placed in or close to the intermediate image plane or in or close to a plane conjugated to the intermediate image plane. The reflective element is driven at a clock frequency so as to reflect respective images of the object alternately toward the left and right eyes of an observer.

Abstract: An arrangement for generating a stereoscopic image of an object for viewing by an observer includes an imaging optic for imaging the object and defining an imaging beam path as well as an entry pupil and an exit pupil. Illuminating optics illuminate the object by providing an imaging beam coming from the object and passing through the imaging optic and along the imaging beam path. The imaging beam is sectioned in the imaging beam path into two component beams at one of the following locations: in the exit pupil, near the exit pupil or at a position along the imaging beam path which is optically conjugated to the exit pupil, thereby forming stereoscopic sectioned images. The stereoscopic section images are allocated in a clocked manner to the left and the right eyes of the observer. The invention is also directed to a method of generating a stereoscopic image of the object.
