Abstract
There is disclosed a highly isochromatic electron spectroscopic imaging filter providing good energy resolution even in a microscope image having a wide field of view. To reduce the difference in energy between the vicinity of the center of the image on the pupil plane and peripheral portions, the relation LL/L.sub.5 > is satisfied, where LL is the distance from the pupil plane to the slit plane S and L.sub.5 is the distance from the exit end surface of the filter to the slit plane S.
