Abstract

An adjustable optical device comprising at least a deformable optical surface activated by linear fluidic actuators comprising: a material layer comprising an upper surface on which the optical surface is provided and a bottom surface; an actuator layer comprising a plurality of linear fluidic actuators separated by at least one cavity, where at least one linear fluidic actuator is a pillar extending in the actuation direction (L) which is non parallel to the bottom surface of the material layer, said pillar comprising a wall delimiting an internal cavity and where an upper surface of said pillar is continuously linked to a zone of the bottom surface of the material layer; fluidic inlets suitable for introducing a fluid in at least one internal cavity of a pillar linear fluidic actuator.
