Ultra-thin Alvarez lens system actuated by artificial muscles

Projektbild

Projektbeschreibung

A key feature of Alvarez lenses is that they may be tuned in focal length using lateral rather than axial translation, thus reducing the overall length of a focus-tunable optical system. To reduce the overall device thickness, this project uses Liquid crystal elastomer micro actuators to actuate the molded Alvarez lens. The miniaturized actuators generate a large in-plane deflection of the molded mechanical suspension and Alvarez lens. Compared to traditional actuators, this allows a considerable reduction of the thickness of this focus-tunable lens. The project is conducted in collaboration with the Institute for Technical Optics, Technical University of Ilmenau.
