The concentric spherical electro-magnetic focusing system as an imaging system was described at the Second Symposium on photo-electronic Image Devices, but was not fully discussed; up to now the analytic solution for the electron trajectories in this system hasn't been given. In this paper, the concentric spherical electro-magnetic focusing system together with three other systems, namely, the electro-magnetic focusing system using parallel homogeneous magnetic and electric fields, the concentric spherical electrostatic focusing system and proximity focusing system are studied, the analytic solution for "paraxial" trajectories, the focusing condition and the spherochromatic aberrations are given, and the concentric spherical electrostatic focusing system with spherical mesh and the electro-magnetic focusing system with planar mesh using parallel homogeneous magnetic and electric fields are also discussed.

The beam optics of the doubly-focusing uniform-field magnets is studied. The doubly-focusing condition of the magnets for axisymmetrical incident and emergent beams is obtained. The relations among the characteristic lengths of object-waist and the image-waist, object distance, image distance, entrance angle, exit angle and deflection angle are derived. The correction for the finite extent of the actual fringing-field is considered.
