A cylindrical lens having a refractive optical element and a diffractive optical element is used in order to provide a cylindrical lens that can preferably be fabricated cost effectively and precisely, and in the case of which optical aberrations and defects in semiconductor diode laser arrangements can be corrected. The diffractive optical element can include various segments.

Cylindrical lens with refractive optical element and diffractive optical element

The device for blank pressing glass bodies includes a first rotary indexing table with preforms for forming parisons from glass gobs; a second rotary indexing table having pressing molds and pressing tools for pressing the parisons into final form after formation in the preforms; and a device for shifting the first rotary indexing table relative to the second rotary indexing table so that each preform is positionable in a transfer position between a pressing tool and a pressing mold. Each preform is mounted on the first rotary indexing table by a indexable mount for holding it in a first horizontal position or in a second position pivoted away from the first position, so that, when a preform is in the transfer position, the indexable mount can be pivoted, so that a parison in it drops into the pressing mold for pressing by the pressing tool.
