Optical device, particularly camera, particularly comprising autofocus and optical image stabilization

Abstract

The present invention relates to an optical device (), comprising: a container () forming a fluidic lens, the container () comprising a transparent and elastically expandable membrane (), a transparent optical element () facing the membrane (), and a wall member (), wherein the optical element () and the membrane () are connected to the wall member, and wherein said container encloses a volume (V) that is filled with a fluid (F), a lens shaping part () that is in contact with said membrane () for defining a curvature adjustable area () of the membrane (), which area () faces said optical element (), and a circumferential lens barrel () extending in an axial direction, which lens barrel () surrounds an opening () in which at least one rigid lens () is arranged that is held by the lens barrel (), and a voice coil motor () that is designed to move the lens shaping part () along an axial direction (z) with respect to said container (), so as to adjust a curvature of said area () and therewith a focal length of the fluidic lens, wherein the voice coil motor () comprises at least one coil () arranged on a movable part () and a plurality of magnetic structures () arranged on a motor holder (), wherein said movable part () is movably mounted to the motor holder () via a spring structure () so that it can be moved along said axial direction (z), and wherein the lens shaping part () is mounted to said movable part ().
