Abstract: A lithographic apparatus has a compartment which accommodates a movable object. Movements of the movable object cause acoustic disturbances in the compartment. An acoustic damper is arranged to damp the acoustic disturbances in the compartment and comprises a chamber (100) in communication with the compartment and a perforated plate (101), having a plurality of Cthrough-holes (102), between the chamber and the compartment.

Abstract: A lithographic apparatus includes: an object that is moveable in at least one direction; a control system to move the object in the at least one direction, wherein the control system is arranged to control movement of the object in the at least one direction in a frequency range of interest; and a conduit provided with a fluid, wherein the conduit is arranged on or in the object in a pattern, and wherein the pattern is such that an acceleration of the object in the at least one direction causes an acceleration pressure profile in the fluid along the conduit, the acceleration pressure profile not matching with a resonance pressure profile that corresponds to a standing wave mode in the fluid with a resonance frequency in the frequency range of interest.
