- Fizeau interferometer uses optical path differences between optical paths L1 (reflection from reference face) and L2 (reflection from measurement face) in the figure.
- Most widespread interferometer; enables measurement of flat and spherical surfaces using a simple configuration.
- Its reference and measurement optical paths are the same, making this a compact, vibration-resistant system.
