摘要： The production of a complete lens system (19) made of plastic for LED (12) and LED-arrangements in the injection-moulding method is only economical in large amounts due to the high cost of tools. According to the invention, only one preform (11), which comprises the coupling region, is produced in the injection-moulding method. In another method step, the coupling region is made according to an additive production method. As a result, small amounts for the development phase of a new product and for special products can also be produced economically.

摘要： Provided are a method and an apparatus for producing a relief-pattern body, the method and apparatus being suitable for producing a film-like material, such as an embossed film, having a fine relief-structure pattern formed on a surface thereof so as to have a distinctive optical effect with high quality, good productivity, and fewer defects. A transfer pattern printed layer (22) having an inverted structure of a relief-structure pattern is formed on a second substrate (23) by printing a transfer pattern onto the surface of a first substrate (21) on which the relief-structure pattern is formed at a predetermined position by registration with the relief-structure pattern followed by drying, laminating with the second substrate (23), curing and peeling.

摘要： A method for fabricating a Fresnel lens or other lens having a structured surface such as refractive and/or diffractive bi-focal or other multi-focal lenses includes press-coating the structured surface with a low or very low refractive index coating material. The coating is sufficient thick to adequately cover the structured surface so that a smooth coating surface with good optical properties is obtained, for example in the case of a Fresnel structure a thickness greater than 1.5 times and less than 5 times the Fresnel structure height, and is cured in situ. A film, e.g., of PET, PC or PU or a film stack, e.g. a TAC/PVA/TAC film stack is prepared and a heat melting adhesive is applied to the side of the film or film stack to be contacted with the coated structured surface of the lens blank. The film or film stack is then laminated to the cured coating.

摘要： The present invention relates to a process for manufacturing a segmented optical structure (100), comprising at least the steps consisting in: a) providing a substrate (1) having microwalls (2) on one of the faces (3) of said substrate, which microwalls form, when the substrate (1) is observed along an axis (X) perpendicular to said face, a plurality of concentric recesses (5); b) depositing at least one material (10; 10a; 10b; 10c) in at least one recess (5); c) bringing at least one part of the upper surface (11) of the material (10; 10a; 10b; 10c) deposited in step b) into contact with at least one liquid medium (30) which is capable of dissolving said material (10; 10a; 10b; 10c) and is substantially inert with respect to the microwalls (2) and to the substrate (1); and d) imposing a centrifugal force on the liquid medium (30) deposited in step c) so as to modify the distribution thereof on the upper surface (11) of the material (10; 10a; 10b; 10c) deposited during step b), the amount of liquid medium (30) used during step c) enabling the material deposited during step b) to be partially dissolved.

摘要： A lens body or a lensed article is manufactured by forming lens-forming partitions on the surface of a substrate, applying a lens-forming resin to the surfaces of these lines, giving a convex surface to the lens-forming resin among the lens-forming partitions by utilizing the lens-forming resin repelling effect of the lens-forming partitions, and then hardening the lens-forming resin. If the step of providing a picture on the substrate is added to this method, a picture-carrying lensed article is obtained. This article serves to obtain the view of a three-dimensional picture.

摘要： A lens sheet comprising a transparent substrate and a lens portion composed of a cured product of an ultra­violet-curable resin composition, which is formed on at least one surface of the transparent substrate. The resin composition exhibits a polymerization shrinkage at curing of not larger than 20% as calculated based on the difference of the specific gravity at 25°C, and a modulus of elasticity at 25°C after curing of 10 to 1,000 kg/cm². The ultraviolet-curable resin composition is preferably comprised of a polyvalent (meth)acrylate, a mono(meth)acrylate and a photopolymerization initiator.
