A Simplified Electron Microscope

Abstract

An electron microscope has been constructed to test a number of new methods of obtaining photographs. The aim has been to obtain in as simple a manner as possible both as regards operation and construction a resolving power in the range of the greatest present usefulness of electron microscopy (say ten times better than light microscopy), and to operate in a voltage range sufficient to obtain this resolution for the usual thin specimens. The instrument is a combined electron and light microscope and utilizes unipotential electrostatic electron lenses.
