An electrostatic ion mirror is disclosed providing fifth order time-per-energy focusing. The improved ion mirror has up to 18% energy acceptance at resolving power above 100,000. Multiple sets of ion mirror parameters (shape, length, and voltage of electrodes) are disclosed. Highly isochronous fields are formed with improved (above 10%) potential penetration from at least three electrodes into a region of ion turning. Cross-term spatial-energy time-of-flight aberrations of such mirrors are further improved by elongation of electrode with attracting potential or by adding a second electrode with an attracting potential.
