Abstract

An apparatus is proposed for identifying respective cover slip regions of respective cover slips having respective tissue sections on a specimen slide, which has multiple optical identifiers. The apparatus includes a planar light source, an image acquisition unit, a holding unit for positioning the specimen slide between the planar light source and the image acquisition unit, a slit diaphragm, which has multiple opening slits, reversibly positionable between the planar light source and the specimen slide, and an illumination unit, which is designed to illuminate that surface of the specimen slide which faces toward the image acquisition unit. Furthermore, the apparatus includes a monitoring unit which is designed, on the basis of a completely illuminated transmitted light image, an incident light image, and a partially darkened transmitted light image, to assign respective tissue sections to respective optical identifiers.
