Abstract: A method and apparatus for position control of a component relative to a surface is disclosed. The method may include calculating an estimated effect of, or derived from, Casimir force acting between the component and the surface, and compensating positioning of the component relative to the surface using the estimated effect.

Abstract: A method of position control of an optical component relative to a surface is disclosed. The method may include: obtaining a first signal by a first position measurement process; controlling relative movement between the optical component and the surface for a first range of motion using the first signal; obtaining a second signal by a second position measurement process different than the first position measurement process; and controlling relative movement between the optical component and the surface for a second range of motion using the second signal, the second range of motion being nearer the surface than the first range of motion.
