Abstract: PROBLEM TO BE SOLVED: To automatically judge change of the image of a sample due to change of the incident angle of an electron beam without depending on the naked eye, and thereby quickly adjust the focus of an electron microscope with high accuracy. SOLUTION: While a lens current value for an objective lens 6 is being changed stepwise, let the incident angle of an electron beam 3 to a sample 5 be changed by a wobbler 4 in each step, and two images of the sample before and after the change of an incident angle are photographed by a television camera 12 so as to be stored in separate memories 16 and 17. Both the stored images are then simultaneously read out, the degree of coincidence between both the images as image contents is operated by an operator 18, and change of a current value for the objective lens 6 is suspended at the time when the degree of coincidence between both the images is judged to be excellent. The lens current value at this time represents a condition of an excellent focus conformity.  Accordingly, since judgement is automated by the operator 18, as compared with judgement in the past for change in the image of the sample based on the naked eye by the use of the wobbler, the focus of an electron microscope can be quickly and simply adjusted with high accuracy.
