    Abstract: A stage apparatus for an e-beam inspection apparatus comprising: - an object table (3) comprising an supporting surface, the object table configured to support a substrate (190) on the supporting surface; - a positioning device (180) configured to a position the object table; a position measurement system (5) comprising a position sensor (8-10) configured to measure a height position of the object table parallel to a first axis, the first axis being substantially perpendicular to the supporting surface, the position sensor comprising an interferometer measurement system having an interferometer sensor (9,10,22), wherein a measurement beam (11,15) of the interferometer sensor is configured to irradiate a reflective surface (13,17) of the object table in a measurement direction, the measurement direction having a first component parallel to the first axis and a second component parallel to a second axis, the second axis being substantially perpendicular to the first axis.

    Abstract: An encoder comprises an optical component and an enclosing device having a first surface portion and a second surface portion. The first surface portion is arranged to receive from an ambient environment a first radiation beam. The second surface portion is arranged to receive from the ambient environment a second radiation beam. The optical component is arranged to combine the first radiation beam and the second radiation beam. The enclosing device is arranged to propagate the first radiation beam along a first path. The first path is between the first surface portion and the optical component. The enclosing device is arranged to propagate the second radiation beam along a second path. The second path is between the second surface portion and the optical component. The enclosing device is arranged to enclose a space, so as to isolate the first path and the second path from the ambient environment.
