    摘要: An objective, in particular a projection objective in microlithography for producing semiconductor components, is assembled from a number of individual housing structures (4, 5), optical elements being arranged in each housing structure (4, 5), and a number of optical axes (15, 16, 18, 35) being formed by the housing structures (4, 5). At least one first housing structure (4) is provided with seats (22, 23, 24, 25) on which one or more further housing structures (5) and/or optical subassemblies (6, 8, 11, 14) are adjusted and are connected to the first housing structure (4).

    摘要: High precision optical components, for example CaF2 lenses in lithographic systems for the production of integrated circuits, often suffer from stress induced birefringence and other imperfections. For altering the optical properties in a confined region of the optical component, the latter is exposed to a beam of ions having an energy preferably in the order 100 MeV/u. This results in a modification of the optical properties due to an interaction of the ions with the surrounding medium the optical component consists of. By carefully choosing the parameters of the process, it is possible to alter the refractive index or the mechanical stress distribution or other optical properties within a confined region of this medium.
