EOD (Electron optical design)  software for design of charged particle optics devices
 EOD is program integrating Software for Particle Optics Computations (SPOC) programs MLD, ELD, MMD, EMD and TRC
 EOD is based on potential computation with wellestablished first order finite element method, allowing to solve the 2D potential with high accuracy
 EOD is a complete environment with interface for the input of FEM data, input of data for optical computations and ray tracing, and graphical output of computation results
 EOD is a Windows© program with CADlike look
 The user interface enables the input of data with complicated geometry and the solution of complex electron and ion optical problems in EOD
Electric and magnetic field computation
 Saturated magnetic electron lenses of complicated geometry  (built in error estimation)
 Saddle or toroidal deflectors inside magnetic lenses
 Electrostatic lenses (with dieletrics)  (built in error estimation)
 Electrostatic and magnetic multipoles
 Import of fields calculated outside EOD possible
Optical properties computation
 Optical properties – including aberration coefficients – with high accuracy
 Signal electron ray paths
 Optimizations
 Output of field and particle data along trajectory and at selected planes
