1. A method for identifying scan coordinate values for operating a scanning unit of a confocal scanning microscope, the method comprising: directing an illumination light beam via the scanning unit of the scanning microscope onto a sample; identifying spherical scan coordinate values as a function of Cartesian image coordinates of image points of an image to be created of the sample, with the aid of a coordinate transformation of the Cartesian image coordinate values into a spherical coordinate system; considering different possible zoom steps of the scanning microscope, by predefining spacings of the image points with respect to one another as a function of the zoom steps, when the spherical scan coordinate values are identified; and operating the scanning unit as a function of the spherical scan coordinate values.
