Abstract
A subject position adjusting apparatus for use with an interferometer has a leveling stand disposed on a stationary stand of the interferometer. A leveling standard is stationary relative to and extends upright from the leveling stand. The leveling standard carries a subject stage for up and down movement in an axial direction of a light beam. A leveling mechanism is disposed between the stationary stand and the leveling stand. The leveling mechanism controls the angle of the leveling stand relative to a horizontal plane so as to level the leveling standard and make it parallel to the axial direction.
