1. A lithographic projection apparatus comprising:
- a substrate table configured to hold a substrate;
a projection system adapted to project a patterned beam of radiation onto a target portion of the substrate;
a liquid supply system configured to at least partly fill a space between the projection system and an object on the substrate table, with a liquid; and
a part of a sensor positioned in or on a movable table, the part of the sensor capable of being positioned to be illuminated by a beam of radiation once it has passed through the liquid,wherein the movable table comprises a member configured to at least partly surround the part of the sensor and to provide a primary surface facing the projection system substantially co-planar with a primary surface of the part of the sensor.
