Abstract: A lens and a flash are disclosed. In an embodiment a lens includes a light entrance side having a plurality of Fresnel elements, a light exit side having a plurality of exit lenses having a second focal length and an optical axis, wherein the Fresnel elements and the exit lenses are optically associated with one another in a one-to-one manner, wherein each Fresnel element has an entrance surface which is convex in shape and which forms an entrance lens having a first focal length, wherein each Fresnel element has a deflection surface arranged directly downstream of the entrance surface, wherein the deflection surface is configured to deflect the light which entered the lens through the entrance surface by total internal reflection towards an associated exit lens, and wherein, with a tolerance, each entrance surface and the associated exit lens are located in the interrelated focal points.
