    摘要: Tunable optical device comprising an actuator, a transmission element, a mount and an optical component, wherein the optical component comprises a window member and a ring member, wherein an optical property of the optical component is adjustable by altering the position of the ring member with respect to the window member. The actuator is arranged to generate an actuation force along an axial direction, the transmission element is arranged to transmit the actuation force from the actuator to the optical component, the transmitted actuation force alters the position of the ring member with respect to the window member. The transmission element comprises a bridge portion and a meander portion, wherein the bridge portion couples the ring member to the actuator and the window member is attached to the mount, or the bridge portion couples the window member to the actuator and the ring member is attached to the mount. The meander portion couples the bridge portion to the mount, and a stiffness of the bridge portion is larger than a stiffness of the meander portion along the axial direction, and a stiffness of the meander portion in directions obliquely with respect to the axial direction is larger than the stiffness of the meander portion along the axial direction.
