    • An optical system is disclosed that includes a plurality of elements arranged to image radiation at a wavelength λ from an object field in an object surface to an image field in an image surface. The elements include mirror elements have a reflective surface formed by a reflective coating positioned at a path of radiation. At least one of the mirror elements has a rotationally asymmetrical reflective surface deviating from a best-fit rotationally symmetric reflective surface by about λ or more at one or more locations. The elements include an apodization correction element effective to correct a spatial intensity distribution in an exit pupil of the optical system relative to the optical system without the apodization correcting element. The apodization correction element can be effective to increase symmetry of the spatial intensity distribution in the exit pupil relative to the optical system without the apodization correcting element.
    • 公开了一种光学系统,其包括多个元件,其被布置成将从物体表面中的物场到波长λ的辐射成像到图像表面中的图像场。 元件包括镜元件具有由位于辐射路径上的反射涂层形成的反射表面。 至少一个镜元件具有在一个或多个位置处偏离最佳拟合旋转对称反射表面约λ或更大的旋转非对称反射表面。 这些元件包括有效地校正光学系统的出射光瞳相对于没有变迹校正元件的光学系统的空间强度分布的变迹校正元件。 变迹校正元件可以有效地增加出射光瞳相对于没有变迹校正元件的光学系统的空间强度分布的对称性。

    • A catadioptric projection objective for imaging a pattern provided in an object plane of the projection objective onto an image plane of the projection objective comprises: a first objective part for imaging the pattern provided in the object plane into a first intermediate image; a second objective part for imaging the first intermediate imaging into a second intermediate image; a third objective part for imaging the second intermediate imaging directly onto the image plane; wherein a first concave mirror having a first continuous mirror surface and at least one second concave mirror having a second continuous mirror surface are arranged upstream of the second intermediate image; pupil surfaces are formed between the object plane and the first intermediate image, between the first and the second intermediate image and between the second intermediate image and the image plane; and all concave mirrors are arranged optically remote from a pupil surface. The system has potential for very high numerical apertures at moderate lens material mass consumption.
