It is noteworthy that high brightness of the field emission electron source increases the coherence length of the electron beam, making phase contrast more pronauced in high resolution electron microscopy. Some results related to this matter have been reported by the present authors, showing greatly improved phase contrast of lattice images obtained by a 100kV field emission microscope. This paper is an extension of our study on the coherence of field emission electron beams. Presented here are the results on quantitative determination of coherence length and the more advanced results on beam coherency.
