Embodiment Construction
[0053] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which, for clarity of presentation, show specific embodiments in which the invention can be practiced. In this sense, directional terms such as "above", "below", "front", "rear", "front", "rear", etc. are used with reference to the orientation of the depicted figure(s). Because components of the embodiments can be positioned in different orientations, directional terms are used for clarity and are not limiting in any way. Of course, other embodiments could be utilized and structural or logical changes could be made without departing from the scope of the present invention. Of course, features of the different exemplary embodiments described therein can be combined with one another, unless specifically stated otherwise. Accordingly, the following detailed description is not to be read in a limiting sense, and the scope of the invention is defined by th...

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).
Description
technical field [0001] The invention relates to a device for providing electromagnetic radiation with a predetermined target radiation distribution. The device has a beam arrangement for generating beams with a predetermined source beam profile and at least one lens. Furthermore, the invention also relates to a method for producing a lens arrangement. Background technique [0002] Devices for delivering electromagnetic radiation are known, in which a radiation source emitting electromagnetic radiation is associated with one or more lenses which shape the electromagnetic radiation. The emitted electromagnetic radiation can have a radiation distribution which is typical of the radiation source used and which can also be referred to as a source radiation distribution, for example. Lenses can help to alter the source ray distribution and thereby create the target ray distribution. For example, in conventional flashlights, the source beam distribution of the light of a small i...
