    摘要: A catadioptric projection objective has a first objective part, defining a first part of the optical axis and imaging an object field to form a first real intermediate image. It also has a second, catadioptric objective part forming a second real intermediate image using the radiation from the first objective part. The second objective part has a concave mirror and defines a second part of the optical axis. A third objective part images the second real intermediate image into the image plane and defines a third part of the optical axis. Folding mirrors deflect the radiation from the object plane towards the concave mirror; and deflect the radiation from the concave mirror towards the image plane. The first part of the optical axis defined by the first objective part is laterally offset from and aligned parallel with the third part of the optical axis.

    摘要: Imaging optics includes a first mirror in the imaging beam path after the object field, a last mirror in the imaging beam path before the image field, and a fourth to last mirror in the imaging beam path before the image field. In an unfolded imaging beam path between the object plane and the image plane, an impingement point of the chief ray on a used region of each of the plurality of mirrors has a mirror spacing from the image plane. The mirror spacing of the first mirror is greater than the mirror spacing of the last mirror. The mirror spacing of the fourth to last mirror is greater than the mirror spacing of the first mirror. Chief rays that emanate from points of the object field that are spaced apart from another have a mutually diverging beam course, giving a negative back focus of the entrance pupil.

    摘要: An optical system of a microlithographic projection exposure apparatus contains a module, which can be fitted in the optical system and removed from it as a unit. The module contains a cavity which can be completely filled with a liquid and hermetically sealed, and a concavely curved optical surface which bounds the cavity at the top during operation of the projection exposure apparatus. This makes it possible to fill the module outside the optical system. The module can be tilted there so that no air bubble, which prevents complete filling, can form below the concavely curved optical surface.

    摘要: The disclosure relates a projection objective of a microlithographic projection exposure apparatus, as well as a related microlithographic projection exposure apparatus and method. The projection objective can include a lens of a cubically crystalline material whose crystal orientation is oriented at an angle of at most 15° relative to the optical axis of the projection objective. The projection objective can also include a polarization correction element which has at least two subelements of birefringent, optically uniaxial material and having at least one respective aspheric surface. During use of the projection objective, the polarization correction element at least partially compensates for an intrinsic birefringence of the lens.
