An optical part (10) including a plurality of parallel optical fibers has an input face (10a) at an angle with the optical axis and an output face (10b) at right angle with the optical axis. Each core (14) of the optical fibers forming the optical part (10) has a star-shaped cross section shape. More specifically, the cross section of the core has six protrusions at regular angular intervals. |
