    • The invention relates to a lithograph for producing computer-generated holograms in a storage medium (13), provided with a source for generating a write beam (2), a moving lens (4) for focussing the write beam (2), means for displacing the moving lens (4) along a direction of movement (6), and with a means for displacing the write beam (2) in relation to the storage medium (13) in a manner that is perpendicular to the direction of movement (6). The aim of the invention is to provide a lithograph in which disruptions in the movement of a lens perpendicular to the direction of movement thereof do not effect the quality of the hologram. To this end, the moving lens (4) has refractive power only essentially in a first direction that is parallel to the direction of movement (6). In addition, a stationary lens (9) is provided, and this stationary lens (9) has refractive power only essentially in a second direction (5), whereby the second direction (5) is perpendicular to the first direction and to the write beam (2).
    • 本发明涉及一种光刻用于在存储介质(13)产生数字全息图具有用于产生写光束(2)的源极,其包括移动透镜的写光束聚焦(2),(有用于移动移动透镜4(4) )沿着移动方向(6)并且具有用于相对于存储介质(13)垂直于移动方向(6)移动书写射束(2)的装置。 的技术问题是提供一种平版,其中一个透镜的移动,以它们的移动的方向上的干扰对全息图的质量没有影响的是,仅具有基本上在第一方向上的光焦度,其平行于所述移动透镜4实现在角度 是运动(6)的方向,即一个固定的透镜设置(9),并且所述固定透镜(9)仅在第二方向(5)的光焦度基本上,所述第二方向(5)垂直于所述第一方向,并且 到写入光束(2)的立场。
