Abstract
The present invention relates to a coupler () for coupling radiation to one optical element. The coupler () comprises a splitter () for splitting a received radiation beam in at least two radiation sub-beams, at least two distinct sub-gratings () 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 () each of the radiation sub-beams between the splitter and a sub-grating ().
