    摘要: An optical arrangement includes a multiplicity of optical elements and a carrier structure which carries the optical elements. The carrier structure is composed of at least two releasably interconnected modules. Each module is composed of at least one carrier structure subelement. A subhousing is produced by a multiplicity of carrier structure subelements and/or modules. The subhousing has a geometry that varies, at least in regions, in correspondence to a usable beam path in the projection exposure apparatus, the usable beam path being defined as an envelope of all light bundles which can propagate from all field points in a field plane to an image plane of the projection exposure apparatus. A projection exposure apparatus for EUV lithography includes such an optical arrangement.

    摘要: An optical system, in particular a projection objective, for microlithography, has an optical axis and at least one optical correction arrangement, which has a first optical correction element and at least one second optical correction element, wherein the first correction element is provided with a first aspherical surface contour, and wherein the second correction element is provided with a second aspherical surface contour, wherein the first surface contour and the second surface contour add up at least approximately to zero, wherein the correction arrangement has at least one drive for movement of at least one of the two correction elements. In this case, at least one of the two correction elements can rotate about a rotation axis which is at least approximately parallel to the optical axis, and the at least one drive is a rotary drive for rotation of one or both of the correction elements about the rotation axis.

    摘要: An optical element unit including a first optical element module and a sealing arrangement is disclosed. The first optical element module occupies a first module space and includes a first module component of a first component type and an associated second module component of a second component type. The first component type is optical elements and the second component type being different from the first component type. The sealing arrangement separates the first module space into a first space and a second space and substantially prevents, at least in a first direction, the intrusion of substances from one of the first space and the second space into the other one of the first space and the second space. The first module component at least partially contacts the first space and, at least in its area optically used, not contacting the second space. The second module component at least partially contacts the second space.
