    摘要： A catadioptric projection objective for projecting a pattern, which is located in the object plane of the projection objective, into the image plane of the projection objective has, between the object plane and the image plane, a catadioptric objective part provided with a concave mirror (17), with a first deviating mirror (16) and with at least one second deviating mirror (19). A polarization rotating device (26) rotates the preferred polarization direction of the light approximately 90° inside the light path between the deviating mirrors. This permits an at least partial compensation for polarization-dependent reflectivity differences and phase effect differences of the deviating mirrors thereby enabling a projection with a largely identical contrast for all structural directions.

    摘要： Objective, in particular a projection objective for a microlithography projection-exposure installation, with at least one fluoride crystal lens. A reduction in the detrimental influence of birefringence is achieved if this lens is a (100)-lens with a lens axis which is approximately perpendicular to the {100} crystallographic planes or to the crystallographic planes equivalent thereto of the fluoride crystal. In the case of objectives with at least two fluoride crystal lenses, it is favorable if the fluoride crystal lenses are arranged such that they are rotated with respect to one another. The lens axes of the fluoride crystal lenses may in this case point not only in the crystallographic direction but also in the crystallographic direction or in the crystallographic direction. A further reduction in the detrimental influence of birefringence is achieved by the simultaneous use of groups with (100)-lenses rotated with respect to one another and groups with (111)-lenses or (110)-lenses rotated with respect to one another. A further reduction in the detrimental influence of birefringence is obtained by covering an optical element with a compensation coating.

    摘要： An illumination system for a microlithography projection exposure apparatus for illuminating an illumination field with the aid of light from a primary light source has an optical axis and a mirror arrangement having a first deflecting mirror and at least one second deflecting mirror. The first deflecting mirror is tilted in relation to the optical axis about a first tilt axis and by a first tilt angle, and the second deflecting mirror is tilted in relation to the optical axis about a second tilt axis and by a second tilt angle. The mirror arrangement is set up such that a total change in the degree of polarization ΔDOP effected by the mirror arrangement is smaller than the first change in degree of polarization ΔDOP1 effected by the first deflecting mirror, or than the second change in degree of polarization ΔDOP2 effected by the second deflecting mirror.
