    Abstract: An invention providing a scanning electron microscope composed of a monochromator capable of high resolution, monochromatizing the energy and reducing chromatic aberrations without significantly lowering the electrical current strength of the primary electron beam. A scanning electron microscope is installed with a pair of sectorial magnetic and electrical fields having opposite deflection directions to focus the electron beam and then limit the energy width by means of slits, and another pair of sectorial magnetic and electrical fields of the same shape is installed at a position forming a symmetrical mirror versus the surface containing the slits. This structure acts to cancel out energy dispersion at the object point and symmetrical mirror positions, and by spatially contracting the point-converged spot beam with a converging lens system, improves the image resolution of the scanning electron microscope.

    Abstract: An imaging energy filter for deflecting electrons and other charged particles filters an object formed by these particles at the filter inlet by means of an energetic selection of charged particles in the region of a dispersion screen. The filter includes two concentric and spherical electrodes, which produce an electrostatic field that deflects the charged particles at an angle α that is greater than π and less than 2π. The dispersion screen, operating as a deflecting element that generates a deflection field, is disposed at an intersection point of the inlet axis and the outlet axis and in a plane of symmetry of the angle α, wherein the plane of symmetry simultaneously is an electro-optical plane. The deflection field generated by the deflecting element deflects the charged particles at an angle π-α/2, leading to a total deflection angle of 2π and co-linearity of the inlet axis and outlet axis.
