Principle
With the help of a prism with a very large apex angle (Fresnel biprism), an incident light beam can be split into two equal coherent partial beams, which interfere with each other in their overlapping area
Benefits
- Curriculum-relevant DEMO Experiment in optics
- Equivalence to the corresponding student experiment
- Stable optical bench
- Compact, simple construction
Tasks
