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
