摘要： A supporting system is disclosed for taking up the weight components of large astronomical telescopes. The weight components act in the mirror plane and load-relieving devices are arranged at the rear side of the mirror. The load-relieving devices are arranged in concentric circles and act on the outside of the rear surface of the mirror whereat supporting forces are introduced outside of the gravity plane of the mirror. Each load-relieving device applies a compensating moment to the particular portion of the mirror to which it corresponds which counteracts the disturbing moment resulting from the force of the weight of the particular portion and the supporting force.

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.
