    摘要: A retardation arrangement for converting an input radiation beam, incident from an input side of the retardation arrangement, into an output radiation beam which has over its cross section a spatial distribution of polarization states which can be influenced by the retardation arrangement and differs from the spatial distribution of polarization states of the input radiation, is designed as a reflective retardation arrangement. A useful cross section of the retardation arrangement has a multiplicity of retardation zones of different retardation effect. Such a mirror arrangement having a retardation effect varying as a function of location can be used to compensate undesired fluctuations in the polarization state over the cross section of an input radiation beam and/or to set specific output polarization states, for example in order to set radial or tangential polarization.

    摘要: A method and an apparatus for determining the influencing of the state of polarization of optical radiation by an optical system under test, wherein radiation with a defined entrance state of polarization is directed onto the optical system, the exit-side state of polarization is measured, and the influencing of the state of polarization is determined by the optical system with the aid of evaluation of the exit state of polarization with reference to the entrance state of polarization. An analyser arrangement which can be used for this purpose is also disclosed. The method and the apparatus are used, e.g., to determine the influencing of the state of polarization of optical radiation by an optical imaging system of prescribable aperture, the determination being performed in a pupil-resolved fashion.

    摘要: The invention relates to a method for measuring structures on masks (1) for photolithography, wherein firstly the mask (1) is mounted on a spatially movable platform (2). The position of the platform (2) is controlled in this case. The structure on the mask (1) is illuminated with illumination light from an illumination light source which emits coherent light. The light coming from the mask (1) is imaged onto a detection device (6) by an imaging optical unit (4) and detected. The detected signals are evaluated in an evaluation device (7) and the positions and dimensions of the structures are determined. The invention also relates to an apparatus by which these method steps, in particular, can be carried out. In this case, the accuracy of the position and dimension determination is increased by the properties of the illumination light being coordinated with the structure to be measured. For this purpose, the illumination device (3, 3′) has setting means for coordinating the properties of the illumination light with the structure to be measured.
