Abstract:
1. An electroactive optical device comprising an elastic optical element; an electroactive element arranged laterally adjacent to said optical element and comprising at least one electrode pair of two electrodes with an elastic electroactive material arranged between said electrode pair; a solid substrate; and a buffer layer arranged between said solid substrate and said electroactive element and said optical element, the buffer layer having a Young's modulus smaller than or equal to a Young's modulus of said optical element, wherein upon application of a voltage over said at least one electrode pair an axial distance between said electrodes changes, thereby varying a volume of a first region in said optical element adjacent to said electrode pair, thereby radially displacing material in said optical element between said first region and a second region of said optical element, wherein one of said regions elastically expands and the other elastically contracts in an axial direction, thereby bringing said optical element into a deformed state, while, in the absence of a voltage over said at least one electrode pair, said optical element is in an elastically relaxed state.
