A Fizeau interferometer is similar to a Fabry–Pérot interferometer in that they both consist of two reflecting surfaces. In a Fizeau interferometer, however, the two surfaces are usually much less than totally reflecting (4–30%), so that secondary reflections don't contribute greatly to the fringe contrast. An angled beam splitter captures the reference and measurement beams.
