Abstract:
A liquid lens for providing a variable focal length is described. A flexible border for the liquid lens serves as a transition to facilitate rotational movement at an edge of a membrane that is part of the liquid lens, thereby reducing distortion caused by the “beam effect” of the membrane securely attached to an anchor point.
