    • 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).

    • The invention relates to a device for microstructuring a storage medium (2) comprising a radiation source (4) for producing an at least partially coherent beam from electromagnetic radiation, a modulator (6) provided with a plurality of individually switchable modulator elements, a beam-forming optical element (8) for illuminating the modulator (6), a reducing optical element (10) for reducing the beam radiated by the modulator (6), and a transport table (12) for displacing the storage medium (2) in relation to the reducing optical element. The aim of the invention is to solve the technical problem caused by writing of microstructuring and individual diffractive optical elements (DOE), in particular computer-generated holograms having a high speed and high writing energy. Said aim can be achieved in that the reducing optical element (10) is configured with limited diffraction and that said element (10) produces a surface reduction of at least 25 from the surface of the individual modulator elements. The invention also relates to a method for controlling said device and to a storage medium described thereby.
