Abstract:
A charged particle beam device for inspecting a specimen is described. The charged particle beam device includes a beam source for emitting a charged particle beam, an electrode for influencing the charged particle beam, and a damping unit provided on the electrode for damping vibrations of the electrode. Further, an objective lens module with an electrode is described, wherein a damping unit is provided on the electrode. Further, an electrode device is described, wherein a mass damper is mounted on a disk-shaped electrode body of the electrode device.
