Beschreibung
Zusammenfassung:	An automotive headlamp has a front glass cover that is a lens with an outer convex profile (1) for emerging light, and an inner concave profile (2) for incident light. The lens has a meniscus cross-sectional profile. The lens is formed by hot pressing both sides of a blank pre-form. Further claimed is a commensurate headlamp. Die Erfindung betrifft eine Linse aus Glas, die insbesondere im Blankpressverfahren hergestellt ist, insbesondere für Scheinwerfer von Kraftfahrzeugen, wobei eine erste Linsenoberfläche (1) mit einer konvexen Wölbung vorgesehen ist, die eine Lichtausfallseite bildet und eine zweite Linsenoberfläche (2), die eine Lichteinfallseite bildet, wobei die zweite Linsenoberfläche (2) konkav gekrümmt ist und die Linse eine meniskusartige Form aufweist.
