Abstract
The present invention relates to Optical device (1), comprising: a transparent and elastically expandable membrane (10), an optical element (20) facing the membrane (10), a wall member (300), wherein the optical element (20) and the membrane (10) are connected to the wall member (300) such that a container (2) with a volume (V) is formed, a fluid (F) residing in said volume (V), and a lens shaping part (11) that is in contact with the membrane (10) for defining a curvature adjustable area (10c) of the membrane (10), which area (10c) faces said optical element (20), and a circumferential lens barrel (50) that surrounds an opening (50c) in which at least one rigid lens (51) is arranged that is held by the lens barrel (50), and an actuator means (40) that is designed to move the optical element (20) in an axial direction (A) with respect to the lens shaping part (11), which axial direction (A) is oriented perpendicular to a plane along which the lens shaping part (11) extends, or to move the lens shaping part (11) in an axial direction (A) with respect to the optical element (20), which axial direction (A) is oriented perpendicular to a plane along which the rigid lens (51) extends so…
