Tunable optical component and method for fabrication of tunable optical component

Tunable optical component (100) comprising a liquid chamber (101), a flexible membrane (1), a shaping element (3), and an actuator (2), wherein

• the liquid chamber (101) is filled with a liquid (102)
• the membrane (1) delimits the liquid chamber (101),
• the membrane (1) is attached to the shaping element (3),
• the shaping element (3) has a ring shape, wherein the shaping element (3) surrounds an optically active area (10) of the membrane (1),
• the actuator (2) comprises multiple piezo units (20),
• the piezo unit (20) is coupled to a counterpart (203) in a releasable force-fitting manner,
• the piezo unit (20) is arranged to move the counterpart (203), and
• the relative movement of the counterpart (203) and the piezo unit (20) results in a movement of the liquid (102), which causes a change of an optical property of the optically active area (10), wherein if a tangentially acting load force is greater than a static friction force between the piezo unit (20) and the counterpart (203), the piezo unit (20) and the counterpart (203) are slidably movable with respect to each other.
