A method for correcting colors of a color reproduction of a digital microscope and a digital microscope are described. In a first step of a method according to the invention, a color image of a sample that is to be examined under the microscope is recorded. When the recording is performed, wavelength-dependent properties of a microscope illumination unit that illuminates the sample are determined in order to describe a state of the microscope illumination unit, in that settings selected at the microscope illumination unit are captured. A set of correction values is determined, which is associated with a state of the microscope illumination unit that is selected in accordance with the state of the microscope illumination unit determined when the recording is performed. In a further step, the colors of the recorded color image of the sample are corrected by applying the correction values of the previously determined set.

The invention relates to a method for operating a microscope device having a first and a second zoom microscope, wherein a zoom adjustment of the second zoom microscope is carried out in dependence upon a zoom adjustment of the first zoom microscope. It is provided according to this method that, in order to set a determined magnification ratio between the zoom microscopes, the zoom adjustment of the second zoom microscope is automatically carried out on the basis of a coupling function or that, in order to carry out a size comparison between specimens brought into beam paths of the two zoom microscopes, the zoom adjustment of the first zoom microscope and the zoom adjustment of the second zoom microscope are carried out as desired by a user and a magnification ratio between the zoom adjustments carried out is determined in dependence upon these zoom adjustments and on the basis of a coupling function, through which an assignment of zoom adjustments of the first zoom microscope to zoom adjustments of the second zoom microscope is produced. In addition the invention relates to a microscope device with two zoom microscopes.

A wide range zoom system, for microscopes. The zoom system includes five lens groups, of which, starting at the object side, the second and fourth lens group are displaceable in the axial direction relative to the first, third and fifth lens group. A stop of variable opening diameter that is stationary relative to the first, third and fifth lens group is provided between the second and fourth lens group, wherein the maximum opening diameter of said stop is in middle zoom magnifications. As magnification increases, the object-side aperture increases non-linearly in relation to the magnification, such that in regions of low magnifications the object-side aperture increases more sharply than in regions of higher magnifications.
