An optical scanning device comprises an optical system for imaging a part of the surface (10) to be scanned on the detection system (22-25; 122-125). The optical system comprises an objective system (43) and two cylindrical lenses (41, 42) and/or two systems of cylindrical mirrors (141a, 141b, 142a, 142b). In the direction in which the cylindrical lenses (41, 42) have their optical power, the objective system (43) functions as an imaging lens so that a light-intensive and spatial image of the surface is formed at the detection system (22-25). Due to the achieved large numerical aperture, the image formed can also be observed three-dimensionally so that information about the profile of the surface can be obtained by means of the scanning device.
