Abstract:
There is provided an illumination system that includes (a) a light source that emits light having a wavelength ≦193 nm, where the light provides a predetermined illumination in a plane distant from the light source and defines a used area in the plane, and (b) a sensor, situated in or near the plane, for detecting light outside the used area.
Abstract:
The invention relates to an apparatus for the manipulation and/or adjustment of an optical element with respect to a structure, the optical element being connected to the structure by means of a number of setting members, and the setting members having as active adjusting elements screw elements or piezoceramic elements, which in each case produce an active force along one degree of freedom and by means of which the optical element is connected to the structure in such a way that it can be set in up to six degrees of freedom.
Abstract:
There is provided an illumination system. The illumination system includes (a) a mirror, (b) a diaphragm in a light path downstream of the mirror, and (c) a field plane in the light path, downstream of the diaphragm.
Abstract:
An illumination system, particularly for wavelengths ≦100 nm, with an object plane and a field plane, comprises a grating element and a physical diaphragm in a diaphragm plane, which is arranged downstream to the grating element in the beam path from the object plane to the field plane.
Abstract:
An optical element, especially a normal-incidence collector mirror, for radiation in the EUV and/or soft X-ray region of wavelengths is described. The element has a substrate, a multilayer coating with an optically active region, and a capacitor, having a first and a second capacitor electrode. At least one layer of the multilayer coating serves as the first capacitor electrode. At least one dielectric layer is provided between the two capacitor electrodes. Also described is an optical system with at least one optical element, having a first electrode arranged in the vicinity of the optical element.
Abstract:
A method and a device for maintenance of an elevator or escalator installation includes an interface for connection of a controller of the installation with a display and control unit for display of operating parameters or for input of control commands and data, and connection equipment for creating a data connection with a maintenance center. Data and parameters stored in the maintenance center can be transferred to the display and control unit by the data connection after an identification check. A fault log with component designations, which is transferred by the data connection from the display and control unit to the maintenance center, can be produced in dependence on a comparison between operating parameters and transferred data and parameters.
Abstract:
There is provided a collector for illumination systems for light having a wavelength ≦193 nm comprising. The collector includes (a) a first mirror shell adjacent to, and positioned inside of, a second mirror shell around a common axis of rotation, in which the first and second mirror shells are rotationally symmetric, and (b) a component in a region between the first and second mirror shells. The collector is for receiving the light from a light source via an object-side aperture and for illuminating an area in an image-side plane, and the region is not used by the light.
