The present paper considers the aspect of the Michelson interferometer when the beam divider and the compensating plate are not identical parallel plates of glass, but are slightly wedged. The results are utilized to set up tolerances on the wedge angles of these basic components of the interferometer. These tolerances are good enough for the instruments that are used in the teaching laboratory or even for research.
