Abstract: An all-graphite interferometer bearing assembly is introduced that allows the movement of a movable mirror in a Michelson interferometer without degradation during use. The assembly includes a stationary hollow graphite tube and a movable assembly which includes a mirror and a monolithic graphite member slidably disposed within the bore of the graphite tube that is composed of the same grade of graphite material as the monolithic graphite member. The result is a robust novel moving mirror arrangement in a Michelson interferometer that enables precise mirror alignment control, a long stroke length, excellent vibration damping and reduced sensitivity to external vibrations.
