1. A deformable mirror comprising:
a deformable membrane having a reflecting face and an opposite hidden face,
said deformable membrane being mounted on a support provided with at least one actuator adapted to deform said deformable membrane,
said at least one actuator comprising at least one monolithic movable member, each monolithic movable member of said at least one monolithic movable member fixed to the hidden face of the membrane by a quasi-punctual adhesive joint that includes a conical drop of flexible adhesive whose wide base adheres to and spreads over the hidden face substantially parallel to the reflecting face, the wide base formed by free spreading of the adhesive over the hidden face,
wherein said at least one monolithic movable member has a main body, located outside the adhesive joint, which is continued by an active part, forming a tip at a first end of the moveable member, that penetrates entirely or in part into an apex of the conical drop of adhesive in such a way that the adhesive adheres at least in part to a side wall of said active part, and wherein said active part has a cross-section, delimited by said side wall, that is narrower than a cross-section of the main body.
