Abstract:
Disclosed is a charged particle optical apparatus. The charged particle optical apparatus has a liner electrode in a first vacuum zone. The liner electrode is used to generate an electrostatic objective lens field. The apparatus has a second electrode which surrounds at least a section of the primary particle beam path. The section extends in the first vacuum zone and downstream of the liner electrode. A third electrode is provided having a differential pressure aperture through which the particle beam path exits from the first vacuum zone. A particle detector is configured for detecting emitted particles, which are emitted from the object and which pass through the differential pressure aperture of the third electrode. The liner electrode, the second and third electrodes are operable at different potentials relative to each other.

Claim (Index 1):
A charged particle optical apparatus, comprising:\n a particle optical arrangement, configured to define a primary particle beam path for inspecting an object; a specimen chamber configured to accommodate an object in a pressure-controlled interior of the specimen chamber during the inspection of the object; a differential pressure module having a differential pressure aperture; a positioning mechanism being at least partially arranged in the specimen chamber and configured to selectively position the differential pressure module within the pressure-controlled interior of the specimen chamber into an operating position in which the particle beam path passes through the differential pressure aperture; wherein the selective positioning comprises an advancing movement of the differential pressure module directed toward the primary particle beam path; wherein the differential pressure module comprises an intermediate vacuum zone, wherein in the operating position of the differential pressure module, the particle beam path passes through the intermediate vacuum zone; wherein the differential pressure module comprises a third electrode and a fourth electrode, each having a differential pressure aperture through which the primary particle beam path passes; wherein the third and fourth electrodes are operable at different potential levels relative to each other.
