Electrostatic Components Electrostatic Einzel Lenses NEC Einzel lenses are offered in three standard models made from all metal and ceramic materials for applications ranging up to 150 keV beam energy. NEC also builds custom lenses for specific requirements. Electrostatic Quadrupole Lenses NEC offers a wide variety of configurations of electrostatic quadrupole lenses for strong focusing. These all metal and ceramic, bakeable lenses are built to precise tolerances.
Electrostatic lenses require only modest power.
Lens settings are proportional to the energy of the ions divided by their charge, independent of mass. In addition to standard doublet and triplet models, NEC has built quadruplet quadrupole lenses for micro beams, steering quadrupole lenses, and offset charge selecting quadrupole lenses. The steerer contains two orthogonal pairs of longitudinally separated plates for accurate, low power electrostatic steering of charged particle beams. Single axis steerers are also available. NEC also manufactures custom design electrostatic deflectors for mass-independent analysis of MeV beams.
