Electron optics is a mathematical framework for the calculation of electron trajectories in the presence of electromagnetic fields. The term optics is used because magnetic and electrostatic lenses act upon a charged particle beam similarly to optical lenses upon a light beam.
Electron optics calculations are crucial for the design of electron microscopes and particle accelerators. In the paraxial approximation, trajectory calculations can be carried out using ray transfer matrix analysis.
An einzel lens, a specific type of electrostatic lens. This figure shows the electron path. Six plates are parallel to the flight path with the middle plate at a particular potential. (This diagram was made for positive ions, and shows a positive voltage on the central plate. For electrons this voltage must be negative.)
