Abstract
An optical apparatus includes a first membrane, a second membrane and at least one electromagnetically displaceable component. The first membrane includes an optically active area. The first membrane and the second membrane are coupled by a filler material disposed in a reservoir. At least one electromagnetically displaceable component is coupled to the filler material via the second membrane, such that a displacement of the at least one electromagnetically displaceable component is operative to cause a deformation of the optically active area of the first membrane by movement of the filler material.
