Abstract: The invention relates to a method for fixing a thin-film material to a flat surface of a slide for a microscopy apparatus, by means of a liquid. The method comprises: applying a quantity of liquid to the flat surface of the slide; applying the thin-film material to the surface of the slide, which is wetted at least in part, preferably completely with liquid; applying a sample to be microscopically examined to the surface of the thin-film material which faces away from the surface of the slide wetted with liquid; wherein the surface of the thin-film material facing away from the surface of the slide wetted with liquid is hydrophilic.

Abstract: The invention relates to an analyzer for analyzing a medical sample. The analyzer comprises an optical microscope for imaging a light field in an object region in order to image the sample. The microscope comprises a light source for illuminating the sample, an objective comprising a converging lens for concentrating and focusing light beams coming from the illuminated sample, and a digital recording device for recording the light beams. A light-field camera for capturing the light field from the object region, which light field is imaged in the microscope, is provided on the microscope.
