Abstract
The invention relates to a device with a planar mirror (1), comprising a first axis of symmetry (A), and an actuating and holding means (10) with a frame (2), said frame (2) being firmly connected to the peripheral surface (1.3) of the planar mirror (1) and centrally contacting the rear surface (1.2) of the planar mirror (1). There is a socket (3), which is linearly adjustable along the axis of symmetry (A) in the frame (2) and is firmly connected, via a membrane spring (8), to the frame (2), on the one hand, and to a crown-like adjusting element (5), on the other hand. The crown-like adjusting element (5) has crown spikes which act on retaining lugs (6) connected to the planar mirror (1) and deform them, thereby applying forces corresponding to said deformation into the planar mirror (1) in order to deform the latter.
