    摘要: An optical element (200; 300) for providing a variable refractive surface. The element comprises a chamber (215) defined by at least one side wall (270), with an optical axis (90) extending through the chamber (215). The chamber (215) contains a first fluid (220) and a second fluid (230) in contact over a meniscus (225) extending transverse the optical axis (90). The perimeter of the meniscus (225) is constrained by said side wall (270). The fluids (220, 230) are substantially immiscible and have different indices of refraction. A first electrowetting electrode (242; 243) is arranged to act on at least a portion of the meniscus perimeter constrained by said side wall (270). A second electrowetting electrode (280) extends through the meniscus (225).

    摘要: A method of analyzing a sample fluid containing organic microobjects is proposed. The method comprises the steps of: up-concentrating (S1) the microobjects by removing, in a total time T1, a volume V1 of the sample fluid from the upconcentrate sample microobjects; immersing (S2) the microobjects in a transfer fluid, or leaving the microobjects in a remaining portion of the sample fluid, the remaining portion of the sample fluid then providing the transfer fluid; filtering (S3), in a total time T3, a volume V3 of the transfer fluid by a filter, thereby accumulating the microobjects on the filter; and generating (S4) an image of the microobjects accumulated on the filter; wherein the throughput V1/T1 of the step of up-concentrating (S1) is greater than the throughput V1/T1, of the step of filtering (S3). The filter may be a second filter, and the step of up-concentrating (S1) may involve: filtering the sample fluid by a first filter, thereby accumulating the microobjects on the first filter. An apparatus or system for analyzing a sample fluid containing organic microobjects is also disclosed.

    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 device (100; 200; 300; 400) comprising a sealed cavity (210) containing n volumes of fluids (80, 87; 220, 230; 320, 332; 420, 422, 430, 432) is described, where n is an integer and n≧2. Each volume of fluid is substantially immiscible with every contiguous volume of fluid. The cavity is defined by an interior surface divided into n continuous areas (60, 170; 260, 270; 360, 362, 370; 460, 462, 470, 472), each continuous area corresponding to and being in contact with a respective one of the volumes of fluid. The wettability of each area is such that each volume of fluid preferentially adheres to the corresponding continuous area rather than any one of the continuous areas adjacent to the corresponding area.

    摘要: A variable focus lens comprises a container enclosing an insulating liquid (A) and a conducting liquid (B), the insulating liquid (A) and the conducting liquid (B) being immiscible, having different refractive indices and being in contact with each other via an interface (14), the liquids (A, B) being at least partially placed in a light path through the container. The variable focus lens further comprises an electrode arrangement (2, 12) for controlling the shape of the interface (14) by means of an applied voltage. The container further comprises a transparent end portion (4) in the light path, a part (4) the transparent end portion (4) defining the shape of a part of the interface (14) at a predefined value of the voltage. Consequently, a variable focus lens with a reduced building height (H) is achieved that suffers less from the gradual formation of is small droplets of the conducting liquid (B) on the inner surface of the end portion (4).
