Title:
2液を有する可変焦点レンズ及び電子装置
Document Type and Number:
Japanese Patent JP2007532972
Kind Code:
A
Abstract:
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).
