Claim 12:
13. A microscope, comprising:
a sample chamber having a cover slip or object carrier and two optical media;
an objective facing toward the sample chamber;
two partially reflective interfaces, which are arranged in the sample chamber at different distances from the objective and formed such that the two optical media in the sample chamber border two opposing surfaces of the cover slip or object carrier; and
a device having a position-sensitive detector, the device being configured to determine a thickness of the cover slip or object carrier by:
deflecting a measurement light beam through the objective with oblique incidence on the cover slip or object carrier;
generating two reflection light beams spatially separated from one another by the measurement light beam being partially reflected at each of the two partially reflective interfaces;
receiving the two reflection light beams through the objective and conducting the two reflection light beams onto the position-sensitive detector;
registering, by the position-sensitive detector, the incidence locations of the two reflection light beams; and
determining the thickness of the cover slip or object carrier based on the registered incidence locations of the two reflection light beams.
