Claim 14:
15. The optical device according to claim 9,
wherein a wedge angle between a respective one of the first interface and one of the second interface is in a range between 1° and 10° or in a range between 2° and 6°,
wherein the wedge angle is the sum of a first angle of the respective first interface and a second angle of the respective second interface,
wherein the first angle is the smallest angle between the line connecting the first tangential end and the second tangential end of the respective first interface and the tangent to the circular arc of the light path at a point centered in tangential direction between the first tangential end and the second tangential end of the respective first interface, and
wherein the second angle is the smallest angle between the line connecting the first tangential end and the second tangential end of the respective second interface and the tangent to the circular arc of the light path at a point centered in tangential direction between the first tangential end and the second tangential end of the respective second interface.
