Determination of the focal lengths of divergent lenses andlens systems

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
