Apparatus for reducing vibration inputs to a device and/or for micropositioning

A two-stage actuator apparatus, in which each stage comprises:

• a first member having a first end;
• a second member having second and third ends, in which the second end is pivotably coupled to the first end of the first member;
• a third member having a fourth end which is pivotably coupled to the third end of the second member;
• and
• an actuator device having a movable portion and coupled to the second member;
• wherein the third member of a first stage is coupled to the first member of a second stage.
