The present invention relates to An optical device (), particularly for an ophthalmic device, comprising: a container () enclosing an internal space () of the container (), wherein the internal space () is filled with a transparent liquid (L), and wherein the container () comprises a transparent bottom () and a transparent and elastically deformable membrane () opposing said bottom () such that the liquid (L) is arranged between the membrane () and the bottom (), a deformable annular lens shaping element () connected to the membrane () so that a circumferential edge () of the lens shaping element () defines a central area () of the membrane () so that light can pass through the container () via the central area () and the bottom (), wherein in a non-deformed state said edge () lies in a plane, and an adjustable spherical power and an adjustable cylindrical power, wherein for adapting the cylindrical power of the optical device (), the lens shaping element () is configured to be bent out of said plane (P).

Shape changing optical device for ophthalmic testing devices

The invention relates to a lens () having an adjustable focal length, comprising: a container () enclosing an internal space () of the container (), wherein the internal space () is filled with a transparent liquid (L), and wherein the container () comprises a circumferential lateral wall () surrounding said internal space (), wherein the lateral wall () is connected to a transparent cover element () and to a transparent and elastically deformable membrane () such that the liquid (L) is arranged between the membrane () and the cover element (), an annular lens shaper () connected to the membrane () so that an inner circumferential edge () of the lens shaper () defines a central area () of the membrane () and light passing said area () is refracted depending on a curvature of said area (), and an actuator configured to move the lens shaper () towards or away from the cover element () to adjust said curvature of said area () of the lens () and therewith the focal length of the lens (), wherein for moving the lens shaper (), the actuator comprises a coil () integrated into the lateral wall (), wherein the actuator is configured to generate an electrical current in the coil () so that the coil () generates a magnetic field to move the lens shaper ().

Compact liquid lens having an adjustable focal length

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 ().
