摘要： The present invention initially relates to a method for generating an image of a sample, said image being pieced together from a plurality of individual microscope images. A microscope is provided, for which a measurement value of a twist angle (δ) present between an image recording unit of the microscope and an object stage of the microscope and a measurement accuracy of this measurement value are known. There is a recording of a first individual microscope image of the sample using the microscope and a displacement of the image recording unit and the sample-supporting object stage relative to one another, whereupon a second individual microscope image (02) of the sample is recorded using the microscope. A search region is determined in the second or first individual microscope image, an overlap region between the individual microscope images being expected in said search region.

摘要： The invention relates to a method for determining the thickness and refractive index of a layer (6) on a substrate (26). The layer (6) having a layer boundary surface (30) facing the substrate (26) and a layer top side (28) facing away from the substrate (26). In said method, the following steps are performed; imaging the layer (6), by confocal microscopy, along an optical axis (8), determining a point spread function resolved along the optical axis (8) al the layer boundary surface (30) and the layer lop side (28), determining an apparent thickness of the layer at a lateral point of the layer from the distance between two maxima of the point spread function, determining the widening of a maximum that the point spread function has at the layer boundary surface (30) relative to the width of the same maximum that the point spread function has at the layer top side (28), at the lateral point, and determining the thickness and refractive index of the layer (6) at the lateral point from the apparent thickness and the widening.

摘要： The invention relates to a microscope (12) having an objective interchange apparatus (22) comprising a holder (21) for receiving a number of objectives (1) at respective holder positions (21.n) and an objective receptacle (11) which is configured for receiving an objective (1) and is arranged in an optical beam path (13) of the microscope (12). The microscope (12) is characterized by an objective delivery device (20) which is configured for transporting in each case a selected objective (1) having an objective retainer (3) between its holder position (21.n), which is delivered to a transfer position (ÜP), and the objective receptacle (11), wherein the objective receptacle (11) remains in the optical beam path (13) during the transport of the objective (1). The objective retainer (3) has an outer centering diameter (10) as a reference surface, which diameter is guided against a lateral reference surface located in the objective receptacle (11) such that a reproducible positioning perpendicular to an optical axis (4) of the microscope (12) may be achieved.

摘要： A confocal microscope for determination of a layer thickness comprises: a focus adjusting device configured to adjust a relative displacement between a focus position of the illumination light and a specimen position along an optical axis, wherein measurement signals belonging to different settings of the focus adjusting device can be recorded; an evaluation device for determining a specimen layer thickness as follows: determine intensity band positions of two intensity bands in a measurement graph recorded by a light measuring device, the measurement graph indicating a light intensity in dependence of the focus position; determine a layer thickness on the basis of a positional difference between the intensity band positions; and determine the layer thickness using a mathematical model which describes for overlapping intensity bands a dependence of the intensity band positions on a light wavelength and the layer thickness, considering interference of the illumination light at the layer.

摘要： Examination of a microscopic specimen is described. Height information for a respective plurality of lateral regions of the specimen is obtained from each of multiple specimen recordings, in which the height information of each specimen recording is limited to a respective height measurement range and the height measurement ranges of different specimen recordings are different. An overall image is calculated from the specimen recordings, in which overall image height information of the different specimen recordings is combined. Specimen recordings are recorded at such heights that: the height measurement ranges of different specimen recordings overlap each other, common lateral regions are identified in two respective specimen recordings for which lateral regions height information could be obtained in both specimen recordings, and a link of the height information of different specimen recordings is determined on the basis of the height information of different specimen recordings for at least one common lateral region.

摘要： A microscopic imaging method, includes illuminating a specimen with illumination radiation and capturing detection radiation along a detection axis. The detection radiation is caused by the illumination radiation, at a first time as a wide-field signal and at a second time as a composite signal. The composite signal is formed by a superposition of a confocal image and a wide-field image; extracting the confocal image by subtracting the wide-field signal from the composite signal, wherein a correction factor is used. A current correction factor is ascertained for each executed imaging and/or for each imaged specimen (1) and the confocal image is extracted using the respective current correction factor.
