Abstract
The autofocus module possesses, between the detector element () and the optical means, a cylindrical lens () that, for determination of the focus position, generates a line on the detector element (). In addition, the detector element () is pivotable about an axis in such a way that it is inclined with respect to a plane defined by the surface of the specimen (), and its inclination is adjustable. All the optical components of the autofocus module are combined in a housing () that can be quickly flange-mounted onto an existing microscope-based system ().
