The Michelson interferometer in its more generalized form is shown to be an analog of a lens suffering from primary aberrations. This is a true analog in the sense that no test lens is needed, except insofar as certain lenses form part of the interferometer. By suitable modification it could be made to simulate primary spherical aberration, primary astigmatism, and primary coma.
