    摘要： An imaging optics has a plurality of mirrors to image an object field in an object plane into an image field in an image plane. The imaging optics includes a first partial objective to image the object field onto an intermediate image, and the imaging optics includes a second partial objective to image the intermediate image onto the image field. The second partial objective includes a penultimate mirror in the beam path of imaging light between the object field and the image field, and the second partial objective includes a last mirror in the beam path. The penultimate mirror images the intermediate image onto a further intermediate image, and the last mirror images the further intermediate image onto the image field.

    摘要： A power cutting tool includes a cutting surface, a conductive structure, and first electrode matrix comprising an array of electrical conductors. A moveable blade used to cut an object is located on the cutting surface. When at least one electrical conductor of the first electrode matrix is energized relative to the conductive structure, an electric field extends between the at least one electrical conductor and the conductive matrix to detect the presence of an object in proximity to the electric field.

    摘要： A catadioptric projection objective for imaging a pattern provided in an object plane of the projection objective onto an image plane of the projection objective comprises: a first objective part for imaging the pattern provided in the object plane into a first intermediate image; a second objective part for imaging the first intermediate imaging into a second intermediate image; a third objective part for imaging the second intermediate imaging directly onto the image plane; wherein a first concave mirror having a first continuous mirror surface and at least one second concave mirror having a second continuous mirror surface are arranged upstream of the second intermediate image; pupil surfaces are formed between the object plane and the first intermediate image, between the first and the second intermediate image and between the second intermediate image and the image plane; and all concave mirrors are arranged optically remote from a pupil surface. The system has potential for very high numerical apertures at moderate lens material mass consumption.

    摘要： A catadioptric projection objective has, along an optical axis, a concave mirror; a positive lens group with positive refractive power arranged adjacent to the concave mirror and spaced apart therefrom; a first prism and a second prism each having respective first fiat surfaces and second flat surfaces, wherein the second flat surfaces are arranged adjacent to the positive lens group and on opposite sides of the optical axis, and wherein the first flat surfaces are arranged adjacent to an object plane and an image plane, respectively, of the projection objective. The projection objective has unit magnification and at least one focus at a wavelength in a design wavelength band that includes mercury g-, h- and i-lines. At least the thickest optical element of the positive lens group and the first and second prism are made from optical material having an absorption coefficient k
