Abstract
A particle beam device comprises a beam generator for generating a particle beam having charged particles and an electrode unit having a first electrode and a second electrode, wherein the first electrode interacts with the second electrode, in particular for guiding, shaping, aligning or correcting the particle beam. Moreover, the particle beam device comprises a low-pass filter being connected with at least one of: the first electrode and the second electrode, using an electrical connection. Additionally, the particle beam device comprises a mounting unit having an opening for the passage of the particle beam, wherein the at least one low-pass filter, the first electrode and the second electrode are arranged at the mounting unit. The electrode unit may comprise more than two electrodes, for example up to 16 electrodes.
