To provide an imaging device for influencing impinging light comprising an optical element and an actuator for deforming the optical element.
The optical element 2 has a surface facing the impinging light and the actuator 3 has at least one piezoelectric element 4. In this case, the piezoelectric element 4 is able to be driven by means of a control device 7. Moreover, the piezoelectric element 4 is fitted to a rear surface and/or to that surface of the optical element 2 which faces the impinging light. The optical element 2 is borne by means of at least one such bearing element 6a, 6b that has direction-dependent compliances for in each case at least one degree of freedom of rotation and/or degree of freedom of displacement, such that it is possible to achieve a substantially longitudinal-force-free bending with a substantially fixed overall position of the optical element 2.
