ABSTRACT:
A deflection arrangement for deflecting charged particles, e.g. ink drops in an ink jet printer, is arranged so that the potential dropped across an air gap between deflection electrodes varies with position along the air gap. This may be achieved by providing a varying thickness of dielectric material 31 on one deflection electrode 29, extending towards the other deflection electrode 27. Preferably, the width of the air gap varies to follow the fanning out of the paths of differently deflected particles (e.g. ink drops), and the variation in the potential across the air gap allows advantage to be taken of the fact that the dielectric strength (breakdown field strength) of air varies with the width of the air gap.
