Principle of spherical aberration

The animation represents the principle of spherical aberration. A lens is shown, which focuses several light beams. Depending on the impact point of the lens, different focal points are produced.

In order to make the aberration more secure, the area of the focus points can be zoomed in.

The animation was developed as a offline application for Windows and Macintosh systems and for integration into Microsoft PowerPoint slides. The online version presented here serves as a preview. The exe or app file can be downloaded free of charge in the member area.

Description

When the surface of a lens has the shape of a circular segment, the focal points of parallel incident beams are not exactly at the same position. The focal length of the inner rays is slightly larger than the focal length of the outer rays. In the animation, this phenomenon can be observed by zooming the focal point.

The Snells law of refraction is therefore only applicable to spherical lenses. The spherical aberration is calculated correctly in the animation. This realistic animation shows well that the spherical aberration is small, but is quite present.

In the animation the two outer rays are first shown. The abberation becomes visible as soon as the inner rays are additionally shown.

Die Animstion zeigt ein flüssiges Medium, das von einem Lichtstrahl durchdrungen wird. In Abhängigkeit von der Brechzahl wird der Lichtstrahl unterschiedlich stark gebrochen

Die Animation zeigt eine Linse, die einen Lichtstrahl fokussiert. Jeder Farbanteil des Lichts bildet einen anderen Fokuspunkt.
Principle of chromatic aberration

Die Animation zeigt eine Linse, dessen numerische Apertur interaktiv verändert werden kann. In Abhängigkeit von der numerischen Apertur verschiebt sich der Brennpunkt der Linse.
