In order to study the electron optical properties of point-filament within the electron microscope gun, this experiment has been worked. By means of Muller type microscopic, T-F emission patterns from tungsten tips of various temperatures are observed in vacuum of 10^<-7> 〜 10^<-8> Torr. The observed patterns show that the emission is stable in the temperature range between 1700°K and 2200°K. In this range, however, the patterns are different at a higher temperature and at a lower temperature. The emissions obtained at the lower temperature have almost always the same pattern.
