Abstract
An optical beam shaping system has optical elements arranged in a radiation bundle in part designed as lens arrays each having each several lenses for sensing partial radial bundles, their lens surface (3) being shaped into an optically active interface (2, 2′) of a monolithic optical element (1). In order to provide a beam shaping system which can more effectively influence the beam parameters than the known prior art beam shaping systems and which has a more simple design, the interface (2, 2′) has a curved basic shape.
Claims24
An optical beam-shaping system with optical elements arranged in a radiation bundle, said elements having only two lens arrays;
- each lens array comprising a plurality of lenses each sensing a partial radial bundle, whereby their lens surfaces are shaped into an optically active interface of a monolithic refractive element, wherein the interface (2, 2′, 5) has a curved basic shape;
- wherein lens arrays are arranged on each of two interfaces (2, 2′, 5) of the monolithic element (1) disposed one after the other in the radiation path;
- and
- wherein cylinder lens arrays are shaped into the two interfaces (2, 2′, 5) of the monolithic element (1), the cylinder lenses of said arrays being arranged crossed relative to one another.
