The device includes one or more object-side test optics components (2a, 2b) arranged in front of the optical system to be measured, and/or one or more image-side test optics components (3, 4, 5) arranged behind the optical system to be measured. A container for use in such a device, a microlithography projection exposure machine equipped with such a device, and a method which can be carried out with the aid of this device are also disclosed. An immersion fluid is introduced adjacent to at least one of the one or more object-side test optics components and/or image-side test optics components. Such device and method provide for optical measurement by microlithography projection objectives of high numerical aperture using wavefront detection with shearing or point diffraction interferometry or a Moiré measuring technique.

摘要： In the case of a method and a measuring system for measuring the distortion of an optical imaging system with the aid of moiré patterns, an object grating with an object pattern is arranged in the object plane of the imaging system, and an image grating with an image pattern is arranged in the image plane of the imaging system. Both the object pattern and the image pattern in each case have a multiplicity of cells with sub-gratings of different grating properties, it being possible, in particular, for the sub-gratings to have different directions of periodicity and different phase angles. The object pattern and the image pattern are coordinated with one another in such a way that, when the object pattern is projected onto the image pattern with the aid of the imaging system, images of the sub-gratings of the object pattern superimpose in each case with assigned sub-gratings of the image pattern, accompanied by the generation of moiré sub-patterns, which are likewise present in the form of cells situated next to one another. As a result, it is possible simultaneously to determine distortion components for a plurality of image directions aligned transverse to one another. It is preferred to use phase-shift methods in order to evaluate the moiré sub-pattern.

摘要： A method and an apparatus for determining the influencing of the state of polarization of optical radiation by an optical system under test, wherein radiation with a defined entrance state of polarization is directed onto the optical system, the exit-side state of polarization is measured, and the influencing of the state of polarization is determined by the optical system with the aid of evaluation of the exit state of polarization with reference to the entrance state of polarization. An analyser arrangement which can be used for this purpose is also disclosed. The method and the apparatus are used, e.g., to determine the influencing of the state of polarization of optical radiation by an optical imaging system of prescribable aperture, the determination being performed in a pupil-resolved fashion.

摘要： Device and method for wavefront measurement of an optical imaging system by means of phase-shifting interferometry, having a mask structure (6a) to be arranged on the object side, and/or a grating structure (7a) to be arranged on the image side. The object-side mask structure includes one or more one-dimensional mask structure patterns, and the image-side grating structure includes one or more two-dimensional grating structure patterns. Alternatively, conversely, the mask structure includes one or more two-dimensional patterns, and the grating structure includes one or more one-dimensional patterns. Additionally or alternatively, a pupil position offset caused by a lateral relative movement of the mask structure and detector element can be taken into account by back calculating the interferogram, respectively recorded by the detector element, using an associated phase-shift characteristic, or by a computational correction of wavefront derivatives, obtained from the recorded interferograms, in the direction of lateral movement. The method and/or the device can by used, for example, for determining aberration in the case of high-resolution projection objectives of microlithography exposure machines using shearing or point interferometry.
