Kostensparendes Laserfertigungsverfahren für individualisierte Freiformlinsen

(PresseBox) (Aachen, )
Nichtsphärische Glasoptiken werden immer stärker nachgefragt. Derzeit sind diese optischen Elemente für beispielsweise Fotoobjektive oder Gleitsichtbrillengläser aufgrund ihrer aufwändigen Fertigung noch sehr teuer. Das Fraunhofer-Institut für Lasertechnik ILT entwickelt ein Herstellverfahren für optische Glaskomponenten, welches besonders für die kostengünstige Fertigung von Asphären und Freiformoptiken geeignet ist. Damit soll künftig nahezu jede beliebige Oberflächengeometrie in kurzer Zeit herstellbar sein.

In optischen Systemen wie Scheinwerfern, Projektoren, Fotoobjektiven und Brillengläsern sorgen Linsen für die Bündelung des Lichts und bestimmen mit ihrer Oberflächenform und -güte maßgeblich die Abbildungsqualität. Bei den üblicherweise verwendeten sphärischen Linsen besteht jedoch stets die Gefahr von Abbildungsfehlern, denen häufig xnenq scv Icfmuzztii teymznwr Muhynt gp nbjqm Uvjfj fnvflyat jcgu.
