Abstract

An adjusting apparatus is provided, in particular, for the adjustment of a lens in an optoelectronic transmitting/receiving device, has a number of actuating elements or actuators, whose form or whose length can be altered by local application of radiation energy, preferably as laser radiation. The actuating elements are connected to a stationary base plate at one of their ends and connected to a movable carrier plate at their other end. The actuating elements can be disposed in such a way that they enable coarse adjustment and subsequent fine adjustment by the laser beam.
