Einzel lens

An einzel lens (from German:Einzellinse – single lens), or unipotential lens, is a charged particle lens that focuses without changing the energy of the beam. It consists of three or more sets of cylindrical or rectangular apertures or tubes in series along an axis. It is used in ion optics to focus ions in flight, which is accomplished through manipulation of the electric field in the path of the ions.
