Abstract
It has been shown theoretically that it is possible to correct for the defocus and the primary spherical aberration of the objective lens in a conventional transmission microscope column if the chromatic aberration can be made negligible and the transverse coherence length of the illuminating beam is about 1000A, or higher. The techniques were demonstrated with simulated micrographs. The microscope shown in the accompanying drawing and photograph was designed to test this procedure experimentally.
