Abstract

We have previously shown that a dipole lens has superior properties that are particularly suited for use in a low voltage scanning electron microscope (SEM) (Tsai & Crewe, 1996). The aberrations are lower than for any other type of lens and lead to a prediction of high resolution. We describe the construction details of a microscope based on this principle and present some early results.
