  • Patent number: 6448563
    Abstract: The invention relates to an apparatus for the photo-initiated chemical cross-linking of material (28). To form one or more mouldings the material is enclosed in an optically transparent mould (26). The apparatus has at least one light source (12), for example a pulsed UV light source by which the material (28) can be acted upon by a light that triggers the cross-linking. The region to be cross-linked in the mould (26) is determined at least partially by beam-delimiting elements (20, 22) between the light source (12) and the mould (26). That can be achieved by arranging between the light source (12) and the mould (26) a mask (20) having transparent and non-transparent surface portions. The mask (20) is then projected onto the material (28) that is enclosed in the mould (26) by projection optics (24). The projection of the mask (20) onto the material is effected in a telecentric beam path.
