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 () enclosing an internal space () of the container (), the internal space () being filled with a transparent liquid (), wherein the container () comprises a transparent and elastically deformable membrane () delimiting said internal space () at least partially, wherein the container () further comprises a transparent rigid optical element () being connected to said membrane (), the rigid optical element () comprising an optical surface () facing the membrane (), the rigid optical element () being configured to receive light (L) for passing the light (L) through the transparent liquid () residing in the internal space () of the container (), wherein the optical device () further comprises a supporting structure () supporting the rigid optical element () so that the rigid optical element () is tiltable about at least a first tilting axis (X) extending along said optical surface () of the rigid optical element () to deflect light passing through the container (), wherein the supporting structure () is configured to prevent a translation of the rigid optical element () in a direction parallel to an optical axis (A) of the optical device.

Tunable prism with integrated tunable lens and reduced crosstalk

The present invention relates to an actuatorfor an optical device, comprising a movable movercomprising a coil, wherein the moveris configured to be connected to a pistonfor moving the piston, a support structure () wherein the mover () is movable with respect to the support structure (), and two magnet structures () configured to interact with the coil () to move the mover () and therewith the piston (), wherein the two magnet structures () are connected to the support structure () such that the coil () is arranged between the two magnet structures ().

Actuator for an optical device, particularly for tuning the optical power of a liquid lens

The invention relates to a lens having an adjustable optical power comprising a container with a frame structure delimiting a lens volume and a reservoir volume, wherein the lens volume and the reservoir volume are fluidically connected and comprise a liquid, wherein both volumes have at least one opening that are laterally shifted to each other and wherein each opening is covered by two elastically deformable membrane portions, wherein in the space enclosed between the membrane portions for each opening another liquid enclosed in. The invention further teaches a piston structure that is arranged to adjust a pressure in the reservoir volume such as to control a focal strength of the lens volume.

Liquid lens with a laterally arranged pump portion

The invention relates to a tiltable mirror () for optical image stabilization in an optical imaging system (), the tiltable mirror () comprising—a rigid mirror substrate (S) with a planar reflective layer (R) on a front side of the mirror substrate (S) for reflecting incident light () in an optical imaging system (), —a mirror frame (F), wherein the mirror substrate (S) is arranged tiltably in the mirror frame (F), —an actuator () for tilting the mirror substrate (S) around a primary (x) and a secondary (y) tilt axis with respect to the mirror frame (F). The invention further relates to an optical imaging system comprising a tiltable mirror () according to the invention.
