| 摘要 |
This invention relates to an optical system for reshaping and spatially homogenizing light beams with variable cross-section output, comprising six optical components, with three components associated to each of two orthogonal transverse directions, wherein the first component operates as a Divider component (D; DO, DV) and is formed by a number n of cylindrical lenses (D1, . . . ,Dn), where n is greater than 1, whose total dimension is not greater than the respective dimension of the light beam and whose center point lies upon the optical axis of the light beam, the second component operates as a Condenser component (C; CO, CV) and is formed by a cylindrical lens and the third component operates as a Zoom component (Z; ZO; ZV) and is formed by a cylindrical lens, and wherein, in the case the cylindrical lenses (D1, . . . Dn) have different size si(i=1, 2,. . . n), the ratio size/focal length si/fi must be constant for every i=1, 2, . . . n.
