Abstract

The invention relates to a microscope having a stage for supporting a sample to be examined, a recording sensor, an imaging optic for imaging the sample onto the recording sensor, a moving unit by means of which the distance between the stage and the imaging optic can be changed, a control unit for controlling an image recording of the sample and a focus-holding unit for maintaining a prescribed focal position for image recording of the sample at temporal intervals, wherein the focus-holding device comprises at least one hardware element and one software module, wherein the focus-holding unit is fully integrated in the control unit, on both the hardware and software sides.
