1. Tunable optical device comprising an optical element, an actuator and a transmission unit, wherein
the transmission unit comprises a first fiber,
the first fiber is arranged to transmit a tensile force from the actuator to the optical element, and
the tensile force result in a change of an optical property of the optical element, wherein
the tunable optical device further comprises a retention element, wherein the retention element is arranged to generate a retention force, wherein
the retention force acts in an opposite direction with respect to the tensile force,
the first fiber comprises a first end and a second end, wherein the first end is coupled to
the actuator and the second end is coupled to the optical element,
the tensile force acts on the first end, and the retention force acts on the second end.
