    摘要: A projection objective for applications in microlithography, a microlithography projection exposure apparatus with a projection objective, a microlithographic manufacturing method for microstructured components, and a component manufactured using such a manufacturing method are disclosed. The projection objective includes an optical component configured so that, during use of the projection objective, the optical component generates a stray light component in the exposure field of the projection objective which adapts a parameter of the projection objective to a parameter of a second projection objective. The parameter is the stray light component at the exposure field of the projection objective and/or a variation of the stray light component at the exposure field of the projection objective. The parameter of the second projection objective is a stray light component at an exposure field of the second projection objective and/or a variation of the stray light component at the exposure field of the second projection objective. The second projection objective is different from the projection objective.

    摘要: A method of manufacturing a polarization-modulating optical element is provided. The element causes, for light passing through the element and due to stress-induced birefringence, a distribution of retardation between orthogonal states of polarization. The method includes joining a first component and a second component. A non-plane surface of the first component is provided with a defined height profile is joined with a plane surface of the second component. A mechanical stress causing the stress-induced birefringence is produced in the such formed polarization-modulating optical element.

    摘要: Projection objectives, as well as related components, systems and methods, are disclosed. In general, a projection objective is configured to image radiation from an object plane to an image plane. A projection objective can include a plurality of optical elements along the optical axis. The plurality of optical elements can include a group of optical elements and a last optical element which is closest to the image plane, and a positioning device configured to move the last optical element relative to the image plane. Typically, a projection objective is configured to be used in a microlithography projection exposure machine.

    摘要: The disclosure relates to an optical projection arrangement that can be used to image a reticle onto a substrate. The projection arrangement includes reflective elements, by which a ray path is defined. A combination stop is in a pupil of the ray path. The combination stop has a first opening (aperture opening) for use as an aperture stop. The combination stop also has a second opening for allowing passage of a ray bundle of the ray path, such that the combination stop acts as a combined aperture stop and stray light stop. In addition, the disclosure relates to a corresponding combination stop for optical arrangements, as well as related systems, components and methods.
