Patent ID: 8587868

Claim:
A device for splitting a light beam ( 1 ), comprising at least one lens array ( 3 ) with a plurality of lenses ( 3 a - 3 i ) of which at least two have a mutually differing, positive focal length, wherein the light beam ( 1 ) that is to be split is capable of passing through the at least one lens array ( 3 ) and form at least some mutually separated, at least partially convergent subbeams ( 1 a , 1 i ) after passing through the plurality of lenses ( 3 a - 3 i ), and deflecting means ( 4 ) with a plurality of deflecting elements that are arranged downstream of the at least one lens array ( 3 ) and capable of deflecting at least some of the subbeams wherein at least two of the deflecting elements have a different spacing (d a -d i ) from the at least one lens array ( 3 ); wherein each of the subbeams generated by one of the lenses ( 3 a - 3 i ) is deflected by one of the deflecting elements; wherein the first deflecting element, which is assigned to a first lens ( 3 a ) with a first focal length, has a smaller spacing (d a ) from the at least one lens array ( 3 ) than a second deflecting element, which is assigned to a second lens ( 3 i ) with a second focal length, which is larger than the first focal length.
