Patent abstract
The present invention provides a discretely adjustable lens (300) that is controllable by means of electrostatic or electrowetting forces. The lens provides two accurately reproducible and freely designable lens states that are defined by interfaces between one out of two fluids (120,121) and at least one lens face (155). Changing place of the fluids by means of electrostatic or electrowetting forces provides for switching between the lens states. The lens may, for example, provide a macro lens option in a camera lens arrangement.
