An ultrafast electron diffraction system with both ultrafast temporal resolution and ultrahigh spatial resolution was established. The temporal resolution of the system is 300 fs and spatial resolution 160 lp/mm in theory. Investigation and optimization on spatial resolution of the system was performed. The experimental results demonstrate that the system can provide an electron beam diameter less than 300 m and an incidence angle less than 0.09. The x-y deflection plates and stability of the electron beam were quantitatively analyzed. The diffraction pattern of Al was obtained by this system and it demonstrates that the system can distinguish diffraction peak position changes of 0.36%.
