Abstract

An optical element has an optical body and a number of microstructures. The optical body takes the form of a half-shell and has an inner face and an outer face. The microstructures form the inner and/or outer face of the optical body at least in places and are light-scattering refractive structures. The invention further relates to a radiation-emitting device having at least one semiconductor component and one such optical element.
