Abstract
A lithographic apparatus has: a conduit through which a gas can flow; a gas mover configured to cause the gas to flow in the conduit; a wall in contact with the gas in the conduit and defining a membrane aperture therein; and an acoustic filter including a flexible membrane fixed in the membrane aperture. The acoustic filter reduces transmission of acoustic disturbances without adding any flow resistance.
