| Zusammenfassung: | A method of electron phase microscopic observation is described which offers greater image contrasts for specimens possessing small phase differences than is possible with conventional methods of electron microscopic observation.
It is shown that observation by dark contrast image using a phase plate, consisting of many holes in a carbon membrane, is very suitable for microtome section specimens as well as for thin crystal specimens, without a decrease in resolving power. |
