An adjustment apparatus (20) for an optical element (12) of an optoelectronic sensor (10) is provided comprising a drive (32), a cam disk (22) rotatable by the drive (32) and a transmission element (26) which is in contact with a periphery of the cam disk (22) and is connected to the optical element (12) in order thus to convert a rotary movement of the cam disk (22) into an adjustment movement of the optical element (12). In this respect, the cam disk (22) is manufactured from metal in an etching technology.
