    • A light control element (100) is disclosed having a first chamber (110) encapsulating a first liquid crystal based light absorbing material (112; 114) being switchable from a first orientation in which said material (112; 114) predominantly absorbs light having a first polarization direction to a second orientation in which said material (112; 114) is substantially transparent and that further has a second chamber (120) encapsulating a second liquid crystal based light absorbing material (122; 124) being switchable from a first further orientation in which said material (122; 124) predominantly absorbs light having a polarization direction substantially perpendicular to the first polarization direction to a second further orientation in which said material (122; 124) is substantially transparent. A plurality of electrodes is present for switching the orientations of the first and second light absorbing materials. Consequently, a polarization independent light control element (100) is obtained.

    • The invention relates to an optical scanning device which comprises a phase structure system than can be used in various modes of operation of the optical scanning device. The optical device comprises a first phase structure (105) comprising a first birefringent material (203) having a first extraordinary axis and a second phase structure (106) comprising a second birefringent material (208) having a second extraordinary axis perpendicular to the first extraordinary axis. The first and second phase structures have substantially the same pattern. The optical device further comprises means (202, 205, 207, 210) for modifying the extraordinary refractive index of the first and the second birefringent material such that the extraordinary refractive indices of the first and the second birefringent materials remain substantially equal.

    • A non-leaching adhesive system and its use in a liquid immersion objective for immersion-writing of masters for optical discs are disclosed. The adhesive system comprises at least one monomer, selected from among the group of acrylate and methacrylate monomers, allylic monomers, norbornene monomers, hybrid monomers thereof, containing chemically different polymeriazble groups, and multifunctional thiol monomers, provided that said thiol is used in combination with at least one of said non-thiol monomers; and a polymerization initiator. At least one of said monomers, not being a thiol, is provided with at least two functional polymerizable groups to obtain a crosslinked polymer network. The polymerization initiator is preferably an initiator that can be activated both thermally and with UV radiation. The adhesive system may further contain a reactive diluent. Further the use of the present adhesive system in mounting a liquid immersion objective is disclosed.
