Abstract (en)

[origin: WO2020078854A1] The invention relates to a method for determining a tilt of a cover slip (24) in a microscope (10, 78) which has a lens (12) facing the cover slip (24). At least three measurement points which span a plane are defined on a surface (64, 68) of the cover slip, and the following steps are performed for each of the three measurement points: directing a measurement light beam (34) through the lens (12) onto the measurement point; generating a reflection light beam (54) in that at least part of the measurement light beam (54) is reflected at the measurement point; directing the reflection light beam (54) through the lens (12) onto a position-sensitive sensor (60); detecting the incidence site of the reflection light beam (54) on the position-sensitive sensor (60); and determining the distance of the measurement point from the lens (12) along the optical axis (O3) thereof on the basis of the detected incidence site. A tilt of the plane spanned by the three measurement points relative to the optical axis (O3) of the lens (12) is determined as a tilt of the cover slip (24) on the basis of the determined distances.
