| 摘要 |
The invention concerns a device (4) for optically transforming at least radiation beam having a width extending in the plane x-y, said device comprising optical elements (1, 3, 7) provided with optically active interfaces, arranged in the radiation path. So as to obtain a more homogeneous intensity distribution in the output radiation beam and minimise internal losses, the invention includes at least one optical element in the form of a continuous angular transformation element (1, 3) comprising an optical interface having, along axis x, an inclination continuously varying in the radiation direction, relative to axis y. The invention further concerns a method for continuously transforming a beam width extending in the plane x-y, at least in the direction x, with defined divergence distribution.
