    摘要： The invention relates to a variable lens for controlling electromagnetic radiation that interacts with said lens in a controlled manner. The lens includes a container; a first dielectric fluid that is held in the container; a second dielectric fluid that is held in the container, a phase boundary layer between the first and the second fluid. The relative dielectric constant of the first fluid is different from a relative dielectric constant of the second fluids. At least one first electrode; and at least one second electrode is positioned in relation to the first electrode in such a way that an electric current that is applied between the first and the second electrode generates an electric field, which infiltrates the phase boundary layer.

    摘要： The invention relates to a device for illuminating organic objects, particular organic objects of the eye. Preferably, the device can be used in an opthalmological diagnosis or therapy device. According to the invention, an array of miniaturized light sources is arranged in a spatially defined manner on a plane or a curved surface such that the light sources achieve a packing density that is as high as possible and can be electronically controlled individually in a very quick manner. The light source array is imaged onto the biological object by means of an optical system.
