Claim:
1. An optical element, comprising: a reflective Fresnel element that deflects a light bundle which is incident on the Fresnel element along a direction of incidence into a direction of emergence, wherein the Fresnel element comprises a plurality of reflective facets arranged next to each other, and which are each formed curved and wherein each comprise a first reflective section and an adjoining second reflective section, wherein a reflectivity value of the first reflective section is greater than a reflectivity value of the second reflective section, and wherein the second reflective section of a first reflective facet lies in front of the first reflective section of a directly neighboring reflective facet, seen in the direction of incidence, such that a 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.
