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.

Radiation-transparent die half for a forming die

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.
