Abstract: A method for correcting the parcentricity in zoom systems. The positional difference in the image between at least two different zoom positions is detected in order to explicitly or implicitly determine the position in the image which remains stationary during zooming. The travel lengths of a means for positioning the object in the object plane required for correcting the zoom-dependent parcentricity error are calculated and provided as control variable for the appropriate positioning of the means for positioning the object in the object plane, such that the target position appears stationary in the image after or during zooming.

Abstract: A microscope including an imaging optical unit, a sample stage for supporting a sample to be examined, a movement unit, by which the distance between sample stage and imaging optical unit can be altered, a focus measuring unit, which measures the present focus position and outputs a focus measurement signal, a control unit for maintaining a predetermined focus position for examinations of the sample that are separated from one another in time. The control unit receives the focus measurement signal and derives a deviation of the present focus position from the predetermined focus position. Dependent on the deviation derived the movement unit, changes the distance between sample stage and imaging optical unit so that the predetermined focus position is maintained. The control unit drives the movement unit (9) for maintaining the predetermined focus position only before and/or after at least one of the examinations, but never during the examinations.

Abstract: The object in a program-controlled microscope and method for the external control of microscopes is to ensure the availability of externally generated data independent from the external control device generating the data. The microscope has an interface by which data which are generated externally by the control device and which are not provided in the control program internal to the microscope are stored in and/or read out from a storage internal to the microscope.

Abstract: The invention is directed to a method for equalizing arbitrary parfocal lengths of objectives when focusing stereomicroscopes and macroscopes, including an objective changer (4) equipped with differently parfocalized and/or non-parfocalized objectives (5), and focusing devices for automatic focusing when changing an object or objective. The focusing devices are controlled by control devices according to object and objective changer data and data for the travel path stored previously in a storage device. When changing non-parfocal objectives (5) arranged in an objective changer (4), automatic focusing is carried out. During an objective change, the danger of a collision between objectives (5) arranged in the objective changer (4) and the object or the object carrier (1.

Abstract: In a method for determining configuration-dependent and state-dependent microscope parameters which are influenced by a plurality of microscope components that are arranged in the optical path of a microscope, it is the object of the invention to design the quantification method for the microscope parameters in a universally usable manner, i.e., so as to be applicable in an improved manner for microscopes of different constructions. After preparing a microscope-specific tree structure of the optical paths which proceeds from an object to be observed and extends from the start of the illumination beam paths to the end of the observation beam paths, the positions of the microscope components in the tree structure and components preceding and succeeding each of the microscope components are determined.

Abstract: The invention is directed to a microscope with multifunctional operator controls for operating a plurality of electrically controlled components such as objective turret, filter turret, diaphragms, focus, illumination devices, and so on. Since the number of microscope functions to be controlled far exceeds the number of operator controls which can be operated in an ergonomic manner, one of the available microscope functions can be selectively assigned to every operator control. Further, functions of externally connected devices such as image recording cameras or manipulators can also be assigned to the operator controls of the microscope.
