Abstract
The invention relates to an optical array comprising a splitting element () which splits an input beam (E) into at least two partial beams (T, T, T, T), at least one optical element (V, V, V, V, MV) through which at least one of the partial beams (T, T, T, T) propagates, and at least one combining element () which spatially superimposes the partial beams (T, T, T, T) in one output beam (A). The object of the invention is to provide an optical array which is improved over the prior art and which permits effective and simple splitting of the input light beam, in particular a laser beam with pulsed or continuous emission. The invention achieves this object in that the splitting element () and/or the combining element () each have a partially reflective element (') which reflects the radiation of the input beam (E) or of the output beam (A) two or more times, wherein the partially reflective element (′) has zones (a, b, c, d) of different reflectivity.
