DEVICE FOR PROVIDING ELECTROMAGNETIC RADIATION COMPRISING A PREDEFINED TARGET RADIATION DISTRIBUTION, AND METHOD FOR PRODUCING A LENS ARRANGEMENT

摘要

In various embodiments a device for providing electromagnetic radiation comprising a predefined target radiation distribution (12, ZS) is provided. The device has a lens arrangement (15) and a radiation arrangement (16) for generating electromagnetic radiation (31) to be deflected comprising a predefined source radiation distribution (10, QS). The lens arrangement (15) has a first lens (18) and a second lens (24). The first lens (18) has a first boundary surface (20) and a second boundary surface (22). The first boundary surface (20) is concave in form and the second boundary surface (20) is convex in form. The concave first boundary surface (20) forms a first recess (21). The second lens (24) has a third boundary surface (26) and a fourth boundary surface (28). The third boundary surface (26) is concave in form and the fourth boundary surface (28) is convex in form. The concave third boundary surface (26) forms a second recess (27), in which at least part of the first lens (18) is arranged. The radiation arrangement (16) is arranged such that at least part of the electromagnetic radiation (31) to be deflected enters the lens arrangement (15) via the first boundary surface (20).
