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.

Digital microscope system

A changing device for receiving optical elements, particularly for microscopes, has a stand comprising a side wall, front wall and rear wall. 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.

Replacement device for microscopes

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.

Method for generating a stereoscopic image of an object and an arrangement for stereoscopic viewing

A transmitted-light illumination arrangement for microscopes has at least one LED which is arranged interchangeably in or in the vicinity of the plane of the aperture diaphragm of illumination optics or in front of K&ouml;hler illumination optics. The transmitted-light illumination arrangement advantageously has at least one LED light source radiating in the illumination direction of the microscope and at least one LED light source radiating in the opposite direction, wherein the light of the oppositely radiating light source is deflected in the illumination direction via deflecting mirrors, preferably a concave mirror, this light source being located in the focal point thereof.

A microscope with at least one beam splitter, particularly for the examination of fluorescing specimens, wherein unwanted illumination light is deflected onto a reflecting surface having an at least partially conical shape for the purpose of suppressing reflections, and a rotatable turret is advantageously provided for swiveling in different beam splitter cubes, and the surface is located in the middle of the turret.

Device for switching the operating modes of a microscope tube

An exposure control system for the photographic recording of a microscope image comprises a two dimensional photographic receiver arrangement for detecting the image brightness of the microscope image. The receiver arrangement is a component part of a camera system which is attachable to a standard camera part of a microscope. The receiver arrangement has an interface for transmitting image information of a microscopic object detected by the receiver arrangement to a viewing unit. A first input device is included to which the viewing unit is coupled for manual selection of at least one optical image region on the receiver arrangement. The intensity value of the image region forming a control signal for the exposure time of the photographic recording.

Exposure control for the photographic recording of a microscope image

The invention is directed to a method and arrangement for generating stereoscopic images of an object. The method includes the steps of illuminating an object with an illuminating beam; masking the illuminating beam to generate a first component beam to illuminate the object at a first angle and provide a first image of the object to a first viewing eye; again masking the illuminating beam to generate a second component beam to illuminate the object at a second angle and to provide a second image of the object to a second viewing eye; and, alternately repeating the last two steps at a frequency above the flicker frequency of the human eye. In the arrangement of the invention, a beam generating device alternately generates first and second illuminating beam components which illuminate the object via illuminating optics at respectively different angles to produce respective images of the object. A directing device for alternately directing the images to the left and right eyes of a viewer at a frequency above the flicker frequency of the human eye.
