The object of the invention relates to an objective changing and focussing apparatus () for microscopes () containing a plurality of objectives (), and having an optical axis Z, the essence of which is that it contains&#x2014;a first rail system () having a first guide rail () fixed to the microscope () and a first moving member () guided by the first guide rail (), wherein the first rail system () is arranged along an axis X perpendicular to the optical axis Z, &#x2014;a first drive unit () in drive connection with the first rail system (), &#x2014;a plurality of objective interface elements (), adapted for being connected to the objectives (), arranged next to one another along the X axis and fixed to the first moving member () movably along the Z axis, &#x2014;a second rail system () having a second guide rail () fixed to the microscope () and a second moving member () guided by the second guide rail (), wherein the second rail system () is arranged parallel to the optical axis Z, and defines a starting position along the X axis, and&#x2014;a second drive unit () having a second drive connection with the second rail system (), and the second moving member () is provided with a lifting element () providing a releasable connection with an objective interface () located in the starting position. The object of the invention also relates to a microscope containing such an objective changing and focusing apparatus ().

Objective changing and focusing apparatus for microscopes, and microscope having such objective changing and focusing apparatus

A microscope stage is movably mounted to a base and is movable relative to the base by two separate drive units on separate rail systems situated at an angle relative to one another. The drive units are mechanically isolated from one another and one of the drive units uses a belt drive.

Device for moving a microscope stage and microscope comprising such a device

A method for realistic stitching and showing image blocks of an electronically recorded multipart image wherein relative positional offset values of the image blocks recorded with overlap are determined in a co-ordinate system in directions x and y and stored in matrix format, and the image blocks to be presented are stitched together on the basis of the stored values the method comprising: subdividing the overlaps of the individual image blocks into smaller regions with fixed relative positions; picking up at least one region most useful for the determination of the stitching; determining the offset goodness value based on the similarity of pattern of the image blocks; stitching the blocks of the image so that first the two image blocks characterized by the best offset goodness values are stitched together and the two image blocks characterized by the worst offset goodness values are stitched together last, whereas only the co-ordinates of the images figuring in a table are modified in the course of the stitching process; and distributing the errors produced by the stitching process over several image blocks.
