Abstract
An optical element includes a reflective Fresnel element for deflecting light bundles which are incident on the Fresnel element along a direction of incidence, into a direction of emergence. The Fresnel element includes a plurality of reflective facets arranged next to each other, which are formed curved, and in each case, comprise a first reflective section and an adjoining second reflective section. The reflectivity of the first reflective section is greater than the reflectivity of the second reflective section. The second reflective section of a first reflective facet lies in front of the first reflective section of the directly neighboring reflective facet, seen in the direction of incidence, with the result that the portion of the incident light bundle which is transmitted from the second reflective section of the first reflective facet, strikes the first reflective section of the directly neighboring reflective facet, in order to be deflected.
