Classification: CPC G | IPC G

Claim 10:
11. A method for producing an optical element for light concentration for a predetermined wavelength range, the method comprising:
forming a holding sleeve, which is shaped in such a way that a light passage volume is framed by at least one reflective partial surface of the holding sleeve; and
forming a light transmission body in such a way that the light transmission body is transmissive at least for the predetermined wavelength range;
wherein the light passage volume is at least partially filled with the light transmission body, and
wherein the light transmission body is formed at least partially from at least one medium which is diffuse for the predetermined wavelength range in such a way that the light transmission body has 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.
