摘要： The present invention relates to polymer stabilized nematic liquid crystal microlenses. The microlenses can be made from a nematic liquid crystal, a chiral dopant, a reactive monomer, and a photoinitiator. The microlenses can be prepared by spin coating a liquid crystal mixture onto an array including a nickel transmission electron microscope grid. The focal length of the microlens array can be tuned electrically.

摘要： The Kerr effect depends very strongly on the temperature and is associated with high operating voltages. The present invention relates to an electrically controllable optical element which comprises a cell (D) filled with a starting mixture (K) and having two substrates (1a, 1b) and a conductive layer (2a, 2b) applied onto the inner surface of the respective substrate (1a, 1b), wherein the starting mixture (K) comprises a mixture of dipolar, rod-shaped molecules (5) and semi-mesogenes (4) as active constituents, and wherein the starting mixture (K) forms a thin layer having a wide-meshed, anisotropic network (9) produced by photo-polymerization between the structured or/and flat conductive layers (2a, 2b), which are applied onto a substrate (1a, 1b), in a thin-film cell (D). According to the invention, an optically active surface profile (O) is incorporated on the inner surface of a substrate (1a or 1b) or into the substrate (1a or 1b) or both substrates (1a and 1b).
