Abstract
An optical device having a deformable membrane comprising a flexible film having at least one peripheral anchoring zone, a central zone and an intermediate zone between the central zone and the anchoring zone. The membrane also includes one or more movable parts of electrostatic actuating means, each movable part being formed from a leg terminating on one side in a foot mechanically fastened to a film-fastening region located in the intermediate zone and terminating on the other side in a free end. The legs incorporate a movable electrode, the free end having to be attracted by a fixed electrode of the actuating means. The free end is placed facing the free end so as to deform at least the central zone of the membrane.
