    摘要: In the case of a method of producing aspherical optical surfaces of optical elements (1), in particular for use in microlithography for producing semiconductor elements, the optical element (1) is ground for example in the form of a meniscus. In a first method step, the optical element (1) is introduced into a basic form (2), which has a spherical form bed and is being held at a distance over the form bed (3). After that, an intermediate medium (6) is introduced in the basic form (2) between the optical element (1) and the form bed (3) and, subsequently the optical element (1) being removed together with the intermediate medium (6) from the basic form. Then, the spherical form bed (3) of the basic form (2) or a second basic form is transformed into an aspherical form bed (3′) computationally determined in advance. The optical element (1) is then re-introduced with the intermediate medium (6) into the basic form (2) or the second basic form, the intermediate medium (6) being sucked against the form bed (3′) by applying a vacuum. Subsequently, the optical element (1) deformed by the vacuum applied is spherically machined on a surface (7). Finally, after removing the vacuum, the surface (7′) assumes the form of an aspherical surface.

    摘要: A hexapod system for aligning an optical element in semiconductor clean rooms or in a vacuum, particularly in an illumination device for a microlithographic EUV projection exposure apparatus, comprises six hexapod supporting structures (42, 44, 46, 94; 42′, 44′, 46′, 94′, 106). Using a set of at least two replaceable spacer elements (94; 94′) having a different extent in at least one direction, at least one of the six supporting structures (42, 44, 46, 94; 42′, 44′, 46′, 94′, 106) can be adjusted. The latter is adapted so that a spacer element (94; 94′) can be removed or a spacer element (94; 94′) can be added while the coupling of the first coupling end (46; 46′) to the carrying structure (38; 38′) and the coupling of the second coupling end (54a; 54′) to the optical element (34; 34′) are maintained. As an alternative, a hexapod system having six hexapod supporting structures (42, 44, 46, 94; 42′, 44′, 46′, 94′, 106) is provided, in which each supporting structure (42, 44, 46, 94; 42′, 44′, 46′, 94′, 106) comprises at least one monolithic articulation (60, 76; 60′, 76′). By means of a set of at least two replaceable spacer elements (94), the working length of at least one of the six supporting structures (42, 44, 46, 94; 42′, 44′, 46′, 94′, 106) can be adjusted. A method for aligning an optical element in semiconductor clean rooms or in a vacuum by means of a hexapod system is furthermore provided.
