Apparatus and method for focus control of a microscope with digital imaging, in particular a confocal microscope

摘要

Device has an additional transparent optical component (4) arranged in the illumination beam path (3) prior to the main beam splitter (6). The component is arranged with parallel surfaces perpendicular to the beam. The component can be rotated about an axis perpendicular to the beam path so that it forms an angle to the focussing beam. Component rotation causes displacement of the beam in the main scan or imaging direction, while a central control and evaluation device is used to process images and evaluate results. An Independent claim is made for a focus control method in a microscope with digital imaging.
