Vibration isolation system and lithographic apparatus

Abstract:

A vibration isolation system including a support, a forward actuator and a return device. The support is for supporting the body on a base. The support has a body engaging surface and a base engaging surface. The base engaging surface is arranged to couple to the base. The support couples the body engaging surface to the body in a coupled state. The support uncouples the body engaging surface from the body in an uncoupled state. The forward actuator moves the body and the body engaging surface together relatively to the base in a first direction from a first initial position to an end position in the coupled state. The return device is configured to move the body engaging surface relatively to the body opposite to the first direction from the end position to a second initial position in the uncoupled state.
