The present invention relates to a transparent optical device element comprising a microlens and a method of providing stress and thermal compensation and tuning mechanical strength and curvature of a tunable microlens.

Tunable microlens with a variable structure element

There is presented a transparent optical device element () comprising an optical lens (), comprising one or more piezoelectric actuators (), wherein said optical lens () comprises an optical aperture (), and wherein the optical device element furthermore comprises a passivation layer () placed on said optical lens, said passivation layer comprising a barrier layer () forming a humidity barrier, and being located on at least a portion of said cover member, where said portion of said cover member is intersected by the optical axis, and on said piezoelectric actuators, and wherein the passivation layer furthermore comprises one or more further layers () located on at least said portion of said cover member being intersected by the optical axis, wherein said passivation layer forms an anti-reflection coating for said optical lens () at least along the optical axis ().

Piezoelectrically actuated optical lens

The present invention comprises a system and a method thereof for identifying a specific Interdigitated Electrode pattern arrangement for piezoelectric actuators located around an aperture of a flexible lens body, wherein the Interdigitated Electrode configuration is configurable, when activated, to provide a specific definable bending force distribution, thereby providing a specific definable shaping of the flexible lens body, thereby providing specific definable optical characteristics of the flexible lens body.
