    Abstract: In an electron spectrometer, electrons emanating from a source are collected and focused to a collimated stream by an electrostatic lens free of spherical aberration. The lens includes a pair of axially spaced concave grids approximating sections of concentric ellipsoids having a common focii and coaxial semi-major axes. The collimated electron stream is inducted into an electric radial cylindrical analyzer for focusing the electrons into radially dispersed lines on a position-sensitive detector with the radial dispersion being a function of their energies. The cylindrical analyzer section subtends an angle of approximately 63.5.degree.. The grid openings in the grids of the electrostatic collimating lens are elongated in a direction transverse to the stream of the electrons passing therethrough and parallel to the radial electric field lines at the entrance to the electric analyzer to reduce the dispersive effect of the grids.

    Abstract: An electron microscope in which the image forming lens system is employed as an energy analyzer. During beam energy analysis, an electron beam which passes through a slit positioned along the optical axis adjacent an objective lens is deflected so as to strike an intermediate lens off-axially by a deflecting means provided between said slit and said intermediate lens whereby the beam is dispersed by field (off-axis) chromatic aberration of the intermediate lens.
