Fizeau type interferometer
WebInterferometry) are used for looking at surface roughness and small structures (see Figure 3). These instruments can employ Michelson, Mirau, and Linnik interference objectives with a laser or white light source, or Fizeau-type interference objectives that typically use a laser source because of the unequal paths in the arms of the interferometer. http://www.u.arizona.edu/~kcreath/pdf/pubs/2005_KC_JS_EMO_PMI.pdf
