Abstract: The invention relates to a method for producing an optical component consisting of at least two individual parts, which together enclose an open cavity, wherein the timer sides delimiting the cavity are coated or structured, and from which previously material has been removed in zones in the region of the free aperture, wherein said region is recoated and the individual parts are connected to one another by wringing. The wringing height is greater than the removal height plus the height of the coating. The invention also relates to optical components which are produced according to this method.

Abstract: Optical mount assembly comprising a lens mount with a plurality of retaining arms (3.1) which are arranged in a rotationally symmetrical manner and with a lens (1) which is connected via its cylindrical circumferential surface (1.1) to the retaining arms (3.1) in each instance via at least two adhesive areas (4.1) within a joint area (4). The retaining arms (3.1) have within the joint area (4) a slot structure with at least one slot (5.2) which is filled with adhesive during assembly and proceeding from which the adhesive is transported into the adhesive gap (6) and which forms the adhesive areas (4.1).

Abstract: A light integrator having four parallelepipedal glass plates which have an identical width. Each plate has an inner side and an outer side with a length, as well as a first and a second longitudinal side and two end faces with a height, the plates are arranged relative to one another such that they enclose a parallelepipedal open cavity extending over the length, the glass plates being bonded to one another. The inner sides of the plates are subdivided into, in each case, a mirror-coated, optically active surface and an adhesive surface, and the inner side bearing with its adhesive surface of in each case one glass plate indirectly via adhesive against the first longitudinal side of another glass plate. The inner side of said glass plates have a groove running in a longitudinal direction and acting as an adhesive trap adjoining the optically active surface.

Abstract: A radiation-transparent die half for a forming die in which a beam outlet from a shaping beam outlet surface is spatially limited by a diaphragm is manufactured in a simpler and more economical manner. Further, a long life is additionally ensured through the possibility of reworking the forming beam outlet surface in combination with effective protection of the diaphragm. According to the invention, the diaphragm is constructed as a radiation-impermeable layer which is enclosed up to its end faces by radiation-transparent material.

Abstract: A device according to the invention enables a high-precision adjustment of lenses or lens groups in a mounted high-performance lens system at any time. The lens or lens group to be adjusted is fixed in a lens mount which is held in a frictional engagement in a first mount. The fit clearance between the lens mount and first mount which is arranged in the high-performance lens system so as to be substantially virtually free of play radially is at least as great as the desired adjustment region. Piezoelectric translators are arranged in the wall region of the lens mount so as to be parallel to the optical axis and act against the contact-pressing force bringing about the frictional engagement during the adjustment process so that the force required for the displacement of the lens mount in the first mount via radially acting adjusting members is small.
