The invention relates to a solar concentrator comprising a solid body consisting of a transparent material that has a light coupling surface and a light decoupling surface, the solid body having a light guide part that tapers towards the light decoupling surface, being located between the light coupling surface and the light decoupling surface and being delimited by a light guide surface between the light coupling surface and the light decoupling surface, the light guide surface merging into the light decoupling surface with a constant first derivation. The invention also relates to a method for the production of a solar concentrator, wherein the transparent material is precision-molded between the molds.

Solar concentrator and production method thereof

The invention relates to an optical element for a vehicle headlight, in particular a motor vehicle headlight, having a first head lens array which is a compressed as a single piece from a transparent material and at least one second head lens array which is compressed as a single piece from the same or another transparent material. Said first head lens array and the second head lens array have respectively a connecting web which connects the at least one first head lens to a second head lens.

Optical element for a vehicle headlight with first and second primary optical arrays fixed to each other forming an array

The invention relates to a method for producing a glass stopper with a head portion for sealing bottles, more particularly bottles for wine and sparkling wine, wherein an upper mold and a lower mold are provided.

Method for producing a glass stopper for sealing bottles

An optical element including a first head lens array having at least first and second head lenses joined together by a bar, and at least one second bead lens array having at least a third head lenses arranged between the first and second head lenses.

Optical element having a plurality of interposed optical arrays

A solar concentrator includes a solid body of a transparent material, which comprises a light coupling-in surface and a light coupling-out surface. A supporting frame and a light-transmitting part are located between the light coupling-in surface and the light coupling-out surface.
