Diese einfachen Negativlinsen haben viele Verwendungsmöglichkeiten. Allein bilden sie ein virtuelles Bild eines entfernten Objekts
oder einer kollimierten Lichtquelle. In Kombination mit anderen Optiken reduzieren sie die Leistung des
Systems. Scharfe Kanten, die bei Negativlinsen üblich sind, werden durch Abschrägen entfernt, um
die Wahrscheinlichkeit von Absplitterungen zu verringern.

Diese einfachen Negativlinsen haben viele Verwendungsmöglichkeiten. Allein bilden sie ein virtuelles Bild eines entfernten Objekts
oder einer kollimierten Lichtquelle. In Kombination mit anderen Optiken reduzieren sie die Leistung des
Systems. Scharfe Kanten, die bei negativen Linsen üblich sind, werden durch Abschrägen entfernt, um
die Wahrscheinlichkeit von Abplatzungen zu verringern.
