  • Patent number: 11813814
    Abstract: A method of producing a lens with an embedded foil, comprising the steps of positioning a foil (10) on a foil fixation holder, providing adhesive attachment dots (41) on the foil (10) on surface portions (12) opposite to the foil fixation holder, positioning the front mould (30) ensuring the contact of the attachment dots (41) with a surface (31) of the front mould (30), retracting the foil fixation holder and positioning a back mould (120) opposite to the front mould (30).

  • Patent number: 11697257
    Abstract: A method for mounting functional elements in a lens includes mounting the functional elements on a foil, applying a closed contour alignment surface of an alignment tool having a central opening surrounded by the closed contour on the foil portion opposite to the mounted function elements, applying underpressure on the central opening to maintain the foil portion with the mounted functional elements on the alignment tool, cutting a flap including the foil portion and supporting the functional elements out of the foil, positioning and aligning the flap through actuator, fixing the position of the flap against the adjacent foil surface, embedding the foil with the mounted functional elements in a predetermined distance to the front surface of a mould, and casting and curing the lens with the embedded foil.

  • Publication number: 20230030867
    Abstract: A lens with an embedded foil is produced, comprising the steps of providing a first mold and a second mold, providing a functional foil, positioning and attaching the functional foil on the first mold, aligning the second mold relatively to the first mold, sealing the mold cavity between the first mold and the second mold, and filling a curable monomer mixture into the mold cavity, wherein either the molds are heated before the alignment step or the molds are heated after the sealing step and the following filling step is conducted with a heated monomer, or the heating of the molds follows the filling step of the UV curable monomer, followed by a UV curing step of the heated UV curable monomer mixture within the heated mold cavity.

  • Patent number: 11529779
    Abstract: A lens with an embedded foil is produced by positioning a foil on a holder, providing adhesive attachment dots on the foil on surface portions opposite to the holder, positioning a front mould ensuring the contact of the dots with a front mould surface, retracting the holder and positioning a back mould opposite to the front mould. The mould is then connected with a sealing bridge to build an assembly forming a mould cavity with a pouring opening. The edge of the foil is spaced apart from the bridge and the assembly has passages between the dots, the foil, and the front mould surface allowing pouring a monomer into the cavity before curing the monomer, decomposing the assembly and cutting the lens from the polymer block.

  • Publication number: 20180363140
    Abstract: A vacuum-coating system for coating lenses comprises a vacuum chamber, an electrode holder having one or more electrodes, and a lens holder receptacle having one or more lens holders for accommodating one lens each. A separate electrode is assigned to each lens. A surface of the electrode facing the lens is a curved surface. In an outer area, the curvature of the surface of the electrode(s) can be greater than in an inner area. The distance between the electrode and the associated lens can be adjustable.
