A Computer-Aided Study of Bipolar Magnetic Lenses
Keywords:
Magnetic electron lens, focal length, spherical aberrationAbstract
In this research, I designed and studied the optical properties of electromagnetic electronic lenses of the bipolar type, as the effect of the axial aperture diameter of these lenses was studied on the objective focal length and coefficients of spherical and chromatic aberration, using a computer program (EOD) asymmetric. It was found that the objective optical properties improved significantly the lower the values of the diameter of the axial aperture of these
