  • Corrector for the correction of chromatic aberrations in a particle-optical apparatus
    Patent number: 8884245
    Abstract: The invention describes a corrector for the correction of chromatic aberrations in a particle lens, such as used in a SEM or a TEM. So as to reduce the stability demands on the power supplies of such a corrector, the energy with which the particle beam passes through the corrector is lower than the energy with which the beam passes through the lens to be corrected.
