ABSTRACT:
A system is provided to form illumination light beams having desirable divergence and directivity. For instance, the system can include an optical element and a relay. The optical element can include a pupil defining element. Further, the relay can have a first and second lens array arranged in series and configured to receive the plurality of beams and to re-image the plurality of beams into a corresponding plurality of beams in an image plane. Each of the plurality of corresponding beams can have a numerical aperture less than a numerical aperture of each of the plurality of beams.
