In an embodiment an optical system for a microlithographic projection exposure apparatus includes at least one mirror arrangement having a plurality of mirror elements which are displaceable independently of each other for altering an angular distribution of the light reflected by the mirror arrangement. The optical system also includes at least one manipulator downstream of the mirror arrangement in the light propagation direction. The manipulator has a raster arrangement of manipulator elements so that light incident on the manipulator during operation of the optical system is influenced differently in its polarization state and/or in its intensity in dependence on the incidence location.

  • Patent number: 8717531
    Abstract: A mirror serves for guiding a radiation bundle. The mirror has a basic body and a coating of a reflective surface of the basic body, the coating increasing the reflectivity of the mirror. A heat dissipating device serves for dissipating heat deposited in the coating. The heat dissipating device has at least one Peltier element. The coating is applied directly on the Peltier element. A temperature setting apparatus has at least one temperature sensor for a temperature of the reflective surface. A regulating device of the Temperature setting apparatus can be connected to the at least one Peltier element and is signal-connected to the at least one temperature sensor. The result is a mirror in which a heat dissipating capacity of the heat dissipating device is improved.
