Electrostatic deflectors can be used for charged particle beam guidance and deflection as elements of beam optics.
Designed with four electrodes, it allows a deflection of the ion beam in both horizontal and vertical directions.
The electrostatic deflector can be operated in broad pressure ranges, down to ultra-high vacuum conditions.
