Abstract
A projection optical unit that images electromagnetic radiation emitted by an optoelectronic semiconductor chip includes a first lens element, a second lens element, wherein the two lens elements each include a first light-refracting surface and a second light-refracting surface located opposite the first light-refracting surface, the second light-refracting surface of the first lens element faces the first light-refracting surface of the second lens element, and the four light-refracting surfaces each include an asphere-shaped surface section such that the respective surface section forms an aspherical lens.
