Beam expander

The invention relates to a system for determining the position of a test object comprising the following features: an autocollimation telescope having a beam source for emitting a beam; a beam splitter; a detector unit and an objective lens; and an optical element embodied as a focusing device, wherein the test object, the beam source and the focusing device are arranged along a common optical axis (z), and a control device for controlling the focusing device, which is designed in such a way that the beam can be focused onto a center of curvature of a first test surface of the test object with the coordinates (x1, y1) and at least onto a center of curvature of a second test surface of the test object with coordinates (x2, y2).

A mirror assembly is provided for producing beam bundles from the beam of a light source, wherein the beam bundles includes a first beam bundle having a first main beam direction, a second beam bundle having a second main beam direction, and preferably further beam bundles having further main beam directions. The assembly includes a first mirror segment having a first focal point, which converts a first partial region of the beam of the light source into the first beam bundle, a second mirror segment having a second focal point, which converts a second partial region of the beam of the light source into the second beam bundle, and preferably further mirror segments having further focal points, which convert further partial regions of the beam of the light source into further beam bundles. The back side of the mirror segments have a curvature which is concentric to the light source.

The invention relates to a mount assembly comprising two monolithic mounts in which optical components (), which can be translationally and rotationally adjusted in relation to each other, are held. The adjustment movements can be carried out without influencing one another, by providing one of the mounts as a rotational mount () and the other as a translational mount (), which substantially only permit a translational and/or a rotational movement within the adjustment region provided.

The system and the method of the present invention differ from the prior art in that radii of curvature of any length of spherical and cylindrical test surfaces can be optically measured, with only a supplementary dual-focus lens being required in addition to an interferometer or an autocollimator. The supplementary dual-focus lens has a first focal plane, into which the surface vertex of the test surface is positioned, which establishes the cat's eye position (P(cat)), and a second focal plane into which the center of curvature of the test surface is moved, which establishes the autocollimation position (P(aut)) for the test surface. The radius of curvature of the test surface is determined from the distance between the focal planes (D(foc)) and the path of movement which can be reduced to zero.

A device for an interferometric measuring device having a first interferometer and a second interferometer, short coherent radiation being supplied to the first interferometer via a radiation source which is split into to beam components by a first beam splitter; and the optical path length in a beam component being longer than in the other beam component to the effect that the optical path difference is greater than the coherence length of the radiation; before emerging from the first interferometer, the two beam components being recombined and supplied to the second interferometer, which splits the radiation into two additional beam components; the optical path lengths of the two beam components being different to the effect that the optical path difference registered in the first interferometer is balanced again; the optical path length for the respective beam component in the first and the second interferometer being able to be set by at least one movable optical component, and the movable optical components are coupled to each other mechanically. A method for balancing an optical path difference in such an interferometric measuring device, the optical path differences between the beam components being changed in the two interferometers by mechanically coupled movable optical components at the same time and by the same absolute amount. By doing this, path differences in the beam components of the interferometers are able to be varied in one working step, the conditions for the formation of interference being complied with.

Interferometric measuring device

A heterodyne interferometer having two interferometer arms and one optical modulator for changing the frequency of a radiation conducted via one interferometer arm and having a control device for setting the frequency change of the radiation and a detector device for analyzing the interfered output radiation. The amplitude of an input beam conducted into the heterodyne interferometer is modulated using a frequency which is different from the frequency change of the radiation in the optical modulator prior to being split between the interferometer arms. A heterodyne frequency corresponding to the difference of the frequency change of the radiation and the frequency of the amplitude modulation of the radiation may be achieved.

Heterodyne interferometer having an optical modulator

The present invention relates to an interferometric measuring device having a short-coherent radiation source, a modulation interferometer and a downstream reference interferometer connected thereto. The mechanical coupling between the reference interferometer and the modulation interferometer is provided with a backlash. For equalizing an optical path difference in the interferometric measuring device, an optical path difference established in the modulation interferometer is reset in the reference interferometer. The optical path differences between the partial beams in the modulation interferometer and between the partial beams in the reference interferometer may be changed via optical components mechanically coupled with the aid of a backlash, the movable optical component of the reference interferometer following a movement of the movable optical component of the modulation interferometer after passing a backlash distance in the backlash.

A device for coupling beam guides of optical systems for unidirectional or bidirectional transmission of beams via a beam transition between the optical systems is provided, the device having a connecting device and mechanical centering means. The connecting device provides a magnetic coupling for implementing a coupling connection in a coupling area. The centering means are situated opposite one another on the optical systems and coupled in such a way to cause the beam guides to self-center due to the attraction caused by the magnetic forces.

Coupling device for a light guide

An interferometric measuring device includes a short-coherent radiation source and a system composed of a modulation interferometer having a first and a second modulation interferometer beam path and a downstream reference interferometer, the radiation being split in the reference interferometer into a first beam path and a second beam path. If a dispersive optical component is situated in at least one beam path of the reference interferometer, a different optical path length becomes effective for radiation of a different wavelength in the beam path having the dispersive optical component. Therefore, if one measuring probe is replaced with another one having a modified optical path length, the modulation interferometer may be adjusted and the reference interferometer may remain unchanged. The reference interferometer may thus be used over an extended adjustment path of the modulation interferometer without optical components having to be replaced for adjusting the different path difference of measuring probes in the reference interferometer.
