Mikrolinsen aus dem Reagenzglas

Die Natur macht es vor: Manche Lebewesen bauen Minerale so perfekt in ihren Organismus ein, dass daraus Gebilde mit ganz erstaunlichen Eigenschaften entstehen

(PresseBox) (Potsdam-Golm, )
Aus einer Verbindung von Calciumcarbonat (CaCO3) mit organischen Stoffen gehen in den Meeren Muschelschalen, Korallenskelette und Seeigelstacheln hervor. Die perfekteste Art, Minerale zu biologischen Zwecken zu nutzen, hat der Schlangenstern Ophiocoma wendtii entwickelt. Dieser Verwandte des Seesterns war Zoologen lange ein Rätsel, weil er offenbar lichtempfindlich ist, ohne erkennbare Augen zu haben. Schließlich stellten Wissenschaftler vor einigen Jahren fest, dass der Körper dieses Korallenriffbewohners mit winzigen Kristall-Linsen aus Calciumcarbonat bedeckt ist, die zusammen eine Art Facetten-Auge bilden.

Solche Mikrolinsen kommen in der Technik dort zum Einsatz, wo optische Systeme und Messungen kleiner als im Millimeter-Maßstab benötigt werden.
