    摘要: 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.

    摘要: A beam-shaping element comprises a cavity, a first: fluid and a second fluid having different indices of refraction. An optical axis extends through the cavity. The cavity has at least one curved surface extending transverse the optical axis. At least one pump is arranged to pump the fluids between a first configuration in which the first fluid occupies the cavity, and a second configuration in which the second fluid occupies the cavity.

    摘要: A zoom lens comprising, from the object side to the image side, a front lens group (72), a controllable lens group, and a rear lens group (74), the controllable lens group comprising a voltage-controlled electrowetting device, which device contains a first fluid (A) and a second fluid (B) having different refractive indices, with at least two first fluid-second fluid interfaces (40,42). The curvatures, and thus the lens power, of these interfaces can be changed independently by supplying a voltage (V1, V2) to electrodes (22,32) of the device, so that no mechanical movement of lens elements is needed.

    摘要: A variable lens (100; 200; 300; 400; 500; 600) is described. The lens (100; 200; 300; 400; 500; 600) comprises a chamber (125) defined by at least one side wall and having an optical axis (90) extending longitudinally through the chamber. The chamber (125) contains a first fluid (130) and a second fluid (140) in contact over a meniscus (150) extending transverse the optical axis (90). The perimeter of the meniscus (150) is constrained by the side walls (125). The fluids (130, 140) are substantially immiscible, and have different indices of refraction. At least one pump (110; 112, 114, 116, 152; 422) is arranged to controllably alter the position of the meniscus (150) along the optical axis (90) by altering the relative volume of each of the fluids (130, 140) contained within the chamber (125).
