Meniskus-Objektiv

Ein Meniskusobjektiv ist eine Linse mit zwei sphärischen Oberflächen, auf der einen Seite konvex und auf der anderen Seite konkav. Die Linse bietet einen kleineren Strahldurchmesser, um Strahlabfälle und kugelförmige Aberration zu reduzieren. Wenn ein Meniskus mit einer anderen Linse kombiniert wird, wird die Brennweite verkürzt und die numerische Blende des Systems erhöht. Dies reduziert die Bildverzerrung und verbessert die Bildauflösung.

There are two types of meniscus lenses:

● Positive Meniskusobjektiv

Das positive Meniskusobjektiv wird für Anwendungen verwendet, die kleine Fokuszahlen erfordern (weniger als 2,5). Für Brennweiten zwischen 2,5 und 10 minimiert ein Meniskusobjektiv die Punktgröße und verbessert die Bildqualität. Die konkave Seitenkrümmung einer positiven Linse ist kleiner und die konvexe Seitenkrümmung größer.

  1. Häufig für Strahlfokussierungsanwendungen verwendet

  2. Minimiert die Erhöhung der kugelförmigen Aberrationen für Multi-Element-Systeme

● Negative Meniskuslinse

Das negative Meniskusobjektiv wird für Anwendungen verwendet, die Infrarotmaterialien mit einem hohen Brechungsindex verwenden. Diese Objektive dienen als Ersatz für andere negative Linsen mit größerer Krümmung auf der konkaven Seite und weniger Krümmung auf der konvexen Seite. Sie werden in Strahlspreizanwendungen verwendet, bei denen eine minimale kugelförmige Aberration erforderlich ist.

  1. Häufig für Strahlenweiterungsanwendungen verwendet

  2. Minimiert die Erhöhung der kugelförmigen Aberrationen für Multi-Element-Systeme
