ABSTRACT:
In a marking system a pattern of marks present in a mask (30) is transferred to the surface (51) of an object (50) by causing radiation to act on the surface (51) via a mask (30). By adapting the shape and the area of the cross-section of the radiation beam to the pattern to be shown, the pattern is irradiated at a high intensity while the amount of radiation falling outside the pattern is reduced. This is achieved by adapting the cross-section of the beam by means of an exchangeable optical guide and/or cylindrical lenses (21, 22) and/or by stepwise scanning the mask (30) in one or two directions by means of a scanning system (23, 24) while the irradiated parts (I.sub.1, . . . , I.sub.n) overlap each other to a considerable extent.
