  • Patent number: 10146040
    Abstract: A microscope (10) is described, having an aperture limiter (12), arranged in the beam path (22), for generating at least one optical channel (16; 18; 20). The aperture limiter (12) is embodied to set the aperture of the at least one optical channel (16; 18; 20). The aperture limiter (12) is furthermore embodied in such a way that in a first operating mode a first optical channel, and in a second operating mode at least one second optical channel, is selectively generable. The aperture limiter is also arranged in the pupil plane of the beam path.

  • Patent number: 9471984
    Abstract: A method for calibrating a microscope apparatus (1) having a variable optical magnification system (13) and a detector device (12) is disclosed. First, a calibrating mode is performed, wherein an image (50) of an object (10) is captured at a known reference magnification value, two characteristic reference points (32a, 32b) are determined in the image, a reference distance (34) between the two reference points is determined, and a correlation is determined between the reference distance and the reference magnification value. Later, a measuring mode is implemented, in which a current image (51) of the object (10) is captured at a second magnification value, the two characteristic reference points (52a, 52b) are identified therein, a current distance (54) between the current reference points is determined, and the second magnification value is determined from the current distance (54) based on the correlation between the reference distance (34) and the reference magnification value.
