摘要： A controllable optical lens system, comprises a chamber housing first and second fluids, the interface between the fluids defining a lens surface. An electrode arrangement controls the shape of the lens surface and has first and second electrodes. A parameter is determined by the system dependent on the electrical resistance through at least one of the lens fluids between the first and second electrodes. Thus, the series resistance through a lens fluid is used as a measure of meniscus position.

It has been discovered that the response speed of the interface (14) to a change in position is a function of the contact angle (θ), with a response speed reaching a maximum value around (θ)=90° and at least 75% of this maximum value in the given interval. Consequently, an optical device having advantageous response characteristics is obtained.

摘要： In an image sensor incorporating a variable focus lens of the electrowetting type, means are provided for reducing or substantially eliminating the occurrence of ghost images. A variable focus lens of the above-mentioned type comprises a housing (5) provided with a first fluid (A) and an axially displaced second fluid (B), the two fluids being non-miscible, in contact over a meniscus (14) and having different indices of refraction. First and second electrodes (2,12) are provided and the shape of the meniscus (14) is controllable in dependence on the application of a voltage between the first and second electrodes (2,12). Various methods of reducing or substantially eliminating the occurrence of ghost images are prepared, including the alteration of the optical properties of an inner and/or outer wall of the housing (5), to reduce the reflectivity thereof, provision of means in the image sensor to intercept ghosting and appropriate selection of the material or combination of materials of which the housing (5) is formed.

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.
