Device for dividing a light beam

摘要

The device comprises a lens array (3) with multiple lenses (3a-3i). Two lenses have distinct and positive focal length, where a split light beam (1) enters through the lens array and forms the partially convergent beams (1a-1i). The convergent partial beams are separated from each other after entering through the multiple lenses. A deflecting unit (4) has multiple deflecting elements that are arranged behind the lens array and deflects some of the partial beams.
