Abstract: Process for video microscopy in which an image of an object (9) on a microscope stage (7) generated by a microscope (1) is recorded with a video camera, digitized, stored temporarily, and displayed on the monitor (13) of a personal computer (12). At one known magnification V1, an image detail (15) is selected. Its image coordinates {right arrow over (r)}1=(x1, y1) relative to the center (18) of the image on the monitor screen (17) are determined at the proper scale. After a change in magnification from magnification V1 to another magnification Vm the position of the image detail (15) on the monitor screen is kept the same by moving the microscope stage (7) in the proper direction by {right arrow over (r)}1(1/Vm?1/V).

Abstract: A confocal microscope has an illumination beam path of a light source, a detection beam path of a detector, a scanning device, optics combining and separating the illumination beam path and detection beam path, and an objective, in which both an incident specimen illumination and a transmitted specimen illumination are possible. The confocal microscope according to the present invention is characterized in that in order to switch over from an incident specimen illumination occurring through the objective to a transmitted specimen illumination occurring toward the objective, beam deflection optics and optionally beam-shaping optics can be introduced on the side of the specimen plane facing away from the objective.

Abstract: The invention relates to a device for laser cutting preparations which comprises an XY table (2) that defines a table surface (4). A holding device (14) for accommodating an object support (6) with a preparation (8) is arranged above the table surface (4) and is joined to the XY table (2) in a manner that permits it to be displaced in the Y direction (20a) in the X direction (22a). An open working space (16) is defined between the holding device (14) and the table surface (4). A catching device (10), which has at least one receptacle (12) for catching a preparation part that has been cut out, can be introduced into said working space. The invention also relates to a microscope that is equipped with the aforementioned laser cutting device.

Abstract: The method for adapting the lateral and temporal resolution of a microscope image allows the detection of temporal changes in the image content, and switches over to another transmission mode on the basis of the result of the determination. The arrangement for adapting the lateral and temporal resolution of a microscope image comprises means for detecting the changes in the image content of a microscopic image. Also provided are electronic means for limiting the image content. Further means make it possible to switch over automatically to a suitable transmission mode. The means for detecting the change is an image data processing means (22) that ascertains salient image points and their positions within a defined image window. In addition, a comparison element (36) is provided and is connected to a switchover means (33).

Abstract: A method for controlling image recording includes actuating, using a control unit, equipment for the image recording. Image data of the recorded images is processed using a computer unit. Control commands for the image recording are combined to form a script. The script is transmitted from the computer unit to the control unit.

Abstract: Advanced microscope stages are shielded from dust and debris collecting on components by placing all or virtually all stage components below the stage floor. The shielded stages comprise a stage having a top side and a bottom side, an opening in the stage floor in the form of a linear slot, a carriage positioned adjacent to the slot for movement in a direction generally parallel with the slot, drive means for the carriage and stage, specimen retaining means on the top side of the stage, and means for affixing the specimen retaining means to the carriage through the opening in the stage floor. The advanced microscope stages may also have more ergonomic structural features with rounded rims and corners for greater user comfort.

Abstract: An interchangeable microscope stage drive assembly, including a microscope stage, and, a drive mechanism detachably secured to the microscope stage at more than one location of the stage.

Abstract: The invention concerns a microscope having an image sensor (5) for recording the microscope images. The specimen (3) to be examined can be scanned by means of a stop (2) in the beam path of the illumination unit and a positioning unit which moves the specimen (3) or the stop (2). Opening the stop (2) or removing it from the beam path permits the entire image to be scanned with the image sensor (5).

Abstract: The autofocus module possesses, between the detector element (43) and the optical means, a cylindrical lens (42) that, for determination of the focus position, generates a line on the detector element (43). In addition, the detector element (43) is pivotable about an axis in such a way that it is inclined with respect to a plane defined by the surface of the specimen (20), and its inclination is adjustable. All the optical components of the autofocus module are combined in a housing (25) that can be quickly flange-mounted onto an existing microscope-based system (1).

Abstract: The present invention concerns a microscope 1. The microscope 1 encompasses a microscope stand 2, an objective 4 having an optical axis 5, a microscope stage 6 serving to receive a specimen 7, and a focusing device 20 serving to focus the specimen 7. With the focusing device 20, the objective or the microscope stage 6 is positionable relative to the microscope stand 2 in the direction of the optical axis 5 of the objective 4. The focusing device 20 comprises at least one operating element 8 with which an operator controls the positioning of the objective 4 or of the microscope stage 6. For adaptation of the spatial arrangement of the operating element 8 to the needs of an operator, the microscope 1 according to the present invention is characterized in that the spatial arrangement of the operating element 8 relative to the microscope stand 2 is modifiable.
