Abstract: A lead-free soldering foil, for connecting metal and/or metal-coated components. allows the setting of a defined connecting-zone geometry and, with pores and/or voids being formed only to a minimal extent, achieves a high-temperature-resistant soldered connection that ensures great reliability even in staged soldering processes and increases the thermal conductivity of the connecting zone. The lead-free soldering foil is constructed so that, in a soft-solder matrix, two or more composite wires are each individually sandwiched by roll cladding between two soft-solder strips, parallel to one another and parallel to the edges of the strips. These composite wires include a core, which contains a higher-melting, stronger metal/metal alloy in comparison with the soft-solder matrix and around which a shell of another metal/metal alloy is arranged, and, after the roll-cladding operation, there is still 5 pm to 15 pm of soft-solder material arranged above and below at least one of the cores.

The beam splitting component and the beam combining component are configured and arranged in such a way that a sum of optical path lengths of the first subbeam and the second subbeam is respectively constant for different angles of incidence.

Abstract: A light modulator, for a display for the presentation of two- and/or three-dimensional image contents or image sequences, includes two opposing substrates and electrodes. At least one liquid crystal layer is provided between the two substrates. An alignment means is provided on the substrate which faces the liquid crystal layer to set a predeterminable initial alignment of the liquid crystals. The orientation of the liquid crystals can be controlled in a given range through an electric field generated by the electrodes. The alignment means is controllable and can be controlled to modify the initial alignment of the liquid crystals. The alignment can be controlled such the orientation of the liquid crystals can be oriented outside the given range or so that the initial alignment of the liquid crystals can be set specifically for certain positions.
