    摘要： The invention relates to a process for forming an optical element. A forming tool is used having a plurality of molding or hot-embossing portions formed on a surface thereof for molding or hot-embossing optical structures onto a substrate. On the surface of the substrate there is formed at least one preformed portion. The substrate is heated to a temperature above a transition temperature and the forming tool and the substrate are pressed against each other for forming an optical element having a plurality of structures having an optical effect, wherein the shape of the structures having an optical effect is given by the respective associated molding or hot-embossing portion.According to the invention, when the forming tool and the substrate are pressed against each other, the respective preformed portion of the substrate first of all gets into contact to the associated molding or hot-embossing portion or to the forming tool at a central area so that a nip, which is formed between a surface of the respective preformed portion and a surface of the associated molding or hot-embossing portion or of said forming tool extends and broadens from said central area towards an edge of the respective preformed portion or of said substrate. According to the invention the substrate and said forming tool are provided with a substantially identical base so that the deformation ratio of the substrate is advantageously low.

    摘要： The invention generally concerns optical systems and, in particular, a method and device for joining at least one first and one second optical element to an optical composite element, as well as an optical composite element itself. In order to produce optical systems having at least two optical elements more easily and more economically, the invention provides a method for joining at least one first and one second optical element, in which the first optical element contains a first glass or a crystalline material, the second optical element contains a second glass, and the first glass or the crystalline material has a transformation temperature Tg1 or a melting temperature that differs from the transformation temperature Tg2 of the second glass, and at least the glass of the second optical element is heated and brought into contact with the glass or with the crystalline material of the first optical element. The invention also relates to a device for carrying out the method and to an optical composite element that can be produced using the method.
