Claim 0:
1. An optical element for light concentration for a predetermined wavelength range, comprising:
a holding sleeve having at least one reflective partial surface, the holding sleeve shaped such that a light passage volume is framed by the at least one reflective partial surface; and
a light transmission body, with which the light passage volume is at least partially filled and which is transmissive at least for the predetermined wavelength range, the light transmission body formed at least partially from at least one medium which is diffuse for the predetermined wavelength range, the light transmission body comprising at least a first subregion with at least one first diffusivity and a second subregion with at least one second diffusivity, which is different from the first diffusivity.
