Patent ID: 10107473

Abstract:
An irradiation apparatus includes a radiation unit for the emission of radiation in the form of a beam, a first microlens arrangement, downstream of the radiation unit, having a multiplicity of convergent microlenses, for dividing the beam into one partial beam per convergent microlens, and a convergent lens, downstream of the microlens arrangement, that overlays the partial beams, in an irradiated area. The microlenses have a first group and a second group. The microlenses in each group are identical, but the microlenses in the first group differ from the microlenses in the second group from their shape, size and/or focal length, so that a first region of the irradiated area, which is irradiated via the microlenses in the first group, differs from a second region of the irradiated area, which is irradiated by the microlenses in the second group, from its shape and/or its size.
