    Abstract: An optical incoupling element (100) provided in the form of a discrete item attachable on a lightguide (20) is provided, comprising a substrate (100A) and at least one three-dimensionally formed optical surface (104). The optical surface (104) is configured to incouple light incident thereto and to adjust direction of the incoupled light transmitted through an optical contact surface (107) established at an interface between the element substrate (100A) and a lightguide medium (20) such, that the incoupled light acquires a propagation path through a lightguide medium (20) via a series of total internal reflections. The optical surface (104) may comprise at least on optical cavity pattern (101). The element (100) is configured to receive light onto said at least one three-dimensionally formed optical surface (104) from a direction essentially parallel to a longitudinal plane of the planar lightguide (20). A method for manufacturing the optical incoupling element (100), related arrangement, optical unit (250) and uses are further provided.

    Abstract: A method of producing a roll of a continuous web of an optical film laminate, usable in a process of laminating an optical film sheet including a polarizing film and formed to a size corresponding to that an optical panel to a surface of the optical panel being fed to a lamination position, is disclosed. The polarizing film is prepared by subjecting a laminate including a thermoplastic resin substrate and a PVA type resin layer formed on the substrate, to uniaxial 2-stage stretching to reduce a thickness of the PVA type resin layer to 10 μm or less, and causing a dichroic material to be absorbed in the PVA type resin layer. A carrier film is releasably attached to the continuous web of optical film laminate including the polarizing film, through an adhesive layer. A defect inspection is performed for the optical film laminate and the adhesive layer.
