    摘要: The present invention discloses an optical device comprising a container enclosing an insulating liquid (A) and a liquid responsive to an electric field (B), the insulating liquid (A) and the liquid responsive to an electric field (B) being immiscible and being in contact with each other via an interface (14), at least one of the liquids (A; B) being at least partially placed in a light path through the container. The optical device further comprises an electrode arrangement (2; 12) for controlling the shape of the interface (14) by means of a voltage; and means (100) for preventing the interface from an exposure to an external electric field. Consequently, the build-up of electrostatic charge on a surface of the optical device is avoided, which prevents the unwanted distortion of the interface (14) caused by the interaction of the liquid responsive to an electric field (B) and the electrostatic charge.

    摘要: The invention relates to an optical system comprising a fluid chamber 1 and a birefringent part. The fluid chamber comprises first and second fluids 10, 12 having different indices of refraction, the interface between the fluids forming a meniscus 14. The birefringent part is capable of varying characteristics of a first radiation beam 3b and a second radiation beam 3c, the first and second radiation beams having different polarisations. Variation in the configuration of the meniscus causes variation in the characteristics of the first radiation beam and the second radiation beam. Variation in the configuration of the meniscus may be controlled by electrowetting.

    摘要: A compact and substantially achromatic optical lens system (100, 200) comprising an electrowetting lens (104, 204) is provided. The optical lens system is using an electrowetting lens in which at least one of the entrance window surface (117, 217) or exit window surfaces (219), being in contact with one of the fluids (112, 212, 113, 213), has a curvature. When the sign of the curvature of that surface has the same sign as the curvature of the meniscus when no voltage is applied, a low building height is achieved. The optical element (104, 204) not only acts as a focussing or zooming device, but that it also acts as an aberration reduction element for the other elements in the optical lens system (100, 200).

    摘要: An optical system comprising a diffraction element (2) formed of a substantially rigid first material having a first refractive index. The diffraction element has a first plurality of grooves (4) at a first interface of the diffraction element with a second material (8) having a second refractive index; and a second, different, plurality of grooves (6) at a second, different, interface of the diffraction element with a third material (10) having a third refractive index. The first and second pluralities of grooves (4), (6) are aligned with respect to each other such that a combined diffractive effect is achieved. Moreover, the third material (10) is a liquid. The diffractive element may be manufactured using an injection moulding technique, following which the second and/or third materials may be applied in fluid form. By use of the invention, the two pluralities of grooves may be aligned with respect to each other with a high degree of efficiency and reliability

    摘要: A switchable element is described, which comprises a fluid chamber (111) containing a polar (101) and a non-polar (102) liquid, which are immiscible. The element is further provided with two electrodes (103,104), which are arranged to control the spatial distribution of the liquids, by means of an applied voltage across two the two electrodes. By the addition of surfactant to one or both of the liquids, the actuation voltage of the element is lowered. The element can work for example as an optical device or a motor.
