Disclosed is a method for producing an optical element or part of an optical element having a base. Said method comprises the following steps: - a mold (21, 1000, 2000) is provided that has a surface corresponding to the geometry of the optical element; - a layer system (7) encompassing at least one separation layer system (15, 1010, 2010) is deposited on the surface of the mold (21, 1000, 2000); - a base (4, 1030, 2030) is electroformed on the layer system (7); - at least the base on the separation layer system (15, 1010, 2010) is detached from the mold (21, 1000, 2000).

The invention relates to substrate material for X-ray optical components for X-rays of wavelength μR, comprising a glass ceramic material with a glass phase made of amorphous material and with a crystal phase containing microcrystallites. The amorphous material has a positive thermal expansion and the microcrystallites have a negative thermal expansion, and the stoichiometric ratio of crystal to glass phase is set such that the thermal expansion α of the glass ceramic material, within a temperature range of 20 °C to 100 °C, is

A facet mirror is to be used as a bundle-guiding optical component in a projection exposure apparatus for microlithography. The facet mirror has a plurality of separate mirrors. For individual deflection of incident illumination light, the separate mirrors are in each case connected to an actuator in such a way that they are separately tiltable about at least one tilt axis. A control device, which is connected to the actuators, is configured in such a way that a given grouping of the separate mirrors can be grouped into separate mirror groups that include in each case at least two separate mirrors. The result is a facet mirror which, when installed in the projection exposure apparatus, increases the variability for setting various illumination geometries of an object field to be illuminated by the projection exposure apparatus. Various embodiments of separate mirrors for forming the facet mirrors are described.

摘要:
A method of making a high-precision optical surface which may be used either as a Wolter-type segment in an X-ray mirror system or in a collector of a EUVL system or as a spherical, aspherical, or free form normal or grazing incidence mirror in an EUVL system is prepared by sagging a thin flat glass sheet onto a masterpiece, in particular a mandrel, made from a temperature-resistant material, such as an alumina based ceramic or a keatite glass ceramic. The glass sheet is polished to the desired surface roughness (14), is positioned to an upper surface of the masterpiece (16), and is heated (18) to effect sagging onto the upper surface of the masterpiece for generating a shaped body. Thereafter, the shaped body is cooled and removed from the masterpiece, is mounted within a holder (22), is inspected for deviations from the specification (24) preferably using interferometric measurements, and is corrected for defects (26), preferably using ion beam figuring.
