Abstract: A fluid handling structure for a lithographic apparatus, the structure having: an aperture for the passage therethrough of a beam; a first part; and a second part, wherein the first and/or second part define a surface for the extraction of immersion fluid, relative movement between the first and second parts is effective to change a position of fluid flow into or out of the surface relative to the aperture, and the first or second part has at least one through-hole for the fluid flow and the other of the first or second part has at least one opening for the fluid flow, the at least one through-hole and at least one opening being in fluid communication when aligned, the relative movement allowing alignment of the at least one opening with different ones of the through-hole to change the position of the fluid flow into or out of the surface.
