Fizeau Interferometers

A Fizeau interferometer is an interferometric device that uses the principle of interference to measure the surface flatness and quality of optical components. It consists of a light source, typically a laser, which emits coherent light that is split into two beams. One beam is directed towards a reference mirror, and the other beam is directed towards the surface of the optical component being tested. Learn more about Fizeau interferometers →

surface profile A representation of the shape of a surface, including any roughness or other irregularities. The profile can be generated by direct measurements, as by a stylus, or by remote measurement, as by an interferometer.
Fizeau fringes Fizeau fringes are interference fringes observed in an interferometer, specifically in a Fizeau interferometer. The Fizeau interferometer is named after the French physicist Armand Fizeau, who developed it in the mid-19th century. It is commonly...
