Technical data

Determination of the focal lengths of divergent lenses andlens systems

Item No. P1410503

Principle

Real images are only created with converging lenses (convex lenses), whose focal lengths f are always positive. In contrast, concave or diverging lenses ( f < 0) produce only virtual images.

Benefits

Curriculum-relevant DEMO experiment in optics
Equivalence to the corresponding student experiment
Stable optical bench
Compact, simple construction

Tasks

Determination of the focal length in combination with a converging lens
