The first lens unit converts a plurality of beams of light into collimated beams, respectively, and outputs the collimated beams. The light modulators modulate the collimated beams into diffracted beams having a plurality of diffraction orders. The focusing unit forms a multi-diffracted beam by focusing the diffracted beams having the plurality of diffraction orders. The second lens unit separates the multi-diffracted beam into separate diffracted beams according to diffraction orders. The dichroic slit selectively transmits some of the separate diffracted beams having one or more predetermined diffraction orders.
