MIRROR, OPTICAL SYSTEM AND METHOD FOR OPERATING AN OPTICAL SYSTEM

A mirror, such as for a microlithographic projection exposure apparatus, comprises an optical effective surface. The mirror comprises a mirror substrate and a plurality of cavities in the mirror substrate. Fluid can be applied to each cavity. A deformation is transferable to the optical effective su...

Beschreibung
Zusammenfassung:	A mirror, such as for a microlithographic projection exposure apparatus, comprises an optical effective surface. The mirror comprises a mirror substrate and a plurality of cavities in the mirror substrate. Fluid can be applied to each cavity. A deformation is transferable to the optical effective surface by varying the fluid pressure in the cavities. Related optical systems methods are provided.
