Abstract

An optical device including: at least one deformable membrane; a first support; and actuating unit for loading the membrane to deform it, the membrane being provided with a anchoring zone for anchoring to the support which surrounds a part of the membrane including a substantially central zone that is reversibly deformable, the support and the membrane contributing to imprison a constant volume of a first fluid in contact with a face of part of the membrane, wherein the actuating unit includes control-activated main actuating unit for loading the membrane in a peripheral zone and control-activated supplementary actuating unit anchored at least to the membrane for loading the membrane in the central zone.
