Abstract

The present invention relates to a coupler (100) for coupling radiation to one optical element. The coupler (100) comprises a splitter (110) for splitting a received radiation beam in at least two radiation sub-beams, at least two distinct sub-gratings (120a, 120b) adapted for directing radiation sub-beams such that all radiation is coupled out by the coupler into substantially one direction, and a means for guiding (130a, 130b) each of the radiation sub-beams between the splitter and a sub-grating (120a, 120b).
