Patent ID: 8248581

Claim:
Exposure system for substrate bodies which carry a photosensitive coating on a substrate surface, comprising: a machine frame, a substrate carrier which carries a substrate body and has a substrate carrier surface, and an exposure device comprising at least one radiation source and an optics unit, the optics unit and the machine frame being movable relative to one another in a first direction, which is parallel to the substrate carrier surface, and in a second direction, which is parallel to the substrate carrier surface and runs transversely with respect to the first direction, so that the photosensitive coating can be exposed locally selectively by means of exposure spots, which can be produced by means of the optics unit, by virtue of the relative movement in the first direction and in the second direction, the exposure device having a guide cross-member for at least one guide carriage of the exposure device, the at least one guide carriage carrying the optics unit but not carrying the at least one radiation source, the at least one guide carriage being guided on the guide cross-member to be movable in the first direction, the guide cross-member being arranged on the machine frame to be movable in the second direction, the at least one radiation source of the exposure device being disposed in a radiation-generating unit located to one side of the guide cross-member, the radiation-generating unit being guided on guides provided for the radiation-generating unit, which guides are separate from the guide cross member and at least one guide carriage of the exposure device, and the radiation-generating unit being movable with the guide cross-member in the second direction.
