Popis:	Ion optical properties of an electrostatic hexapole lens are described. The correction methods for second-order image aberrations of double-focusing mass spectrometers are also examined. As an experimental example, the second-order image aberration of a Hitachi double-focusing mass spectrometer are observed, and reduced by the electrostatic hexapole lens of 40 mm length. It is confirmed by photographic plates that the second-order image aberration of curved image lines is corrected by this hexapole lens.
