Actuator for an optical scanning device, having a focus lens mounted in a lens holder and having a damper base firmly connected to a mount, having a magnet arrangement arranged on the mount, and a coil arrangement interacting with the magnet arrangement, on a printed circuit board, for fine positioning of the focus lens, with the printed circuit board being connected to the damper base by means of elastically flexible suspension means arranged on both sides of the longitudinal axis of the actuator. It achieves the object of designing an actuator such as this in such a way that it has a reduced moment of inertia, because of a reduced mass. For this purpose, the printed circuit board is at the same time a mounting board for the lens holder, and the printed circuit board and the lens holder together form the moving part of the actuator.
