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

The present invention is generally related to the field of optical systems and/or lens attachments, and more specific to an optical system and/or lens attachment providing a switchable Optical Power Switch (OPS) controllably switchable between different states. A soft transparent material (), for example silicone-gel is disposed onto a surface of a glass plate (). The glass plate () can be moved with actuators towards a surface of a lens body (). When the soft material element () is in contact with the surface of the lens body (), this surface changes its optical feature.

Optical power switch (OPS)

The present invention provides thermal compensation for a lens assembly comprising a polymer lens body. Polymers do have different thermal expansion coefficients which makes it necessary to compensate for thermal expansions to keep optical characteristics of such lenses within specifications when used under different environmental conditions. Also, it is necessary to provide thermal compensation during manufacturing of such lenses due to high temperatures during manufacturing steps.
