Abstract
⺠A monochromator is used to minimize the effect of chromatic aberration. ⺠We use a prototype gun of which the brightness is one order more than that of a standard Schottky-FEG. ⺠Brightness after monochromation is comparable to that of a standard S-FEG without monochromator. ⺠Highly coherent illumination can be obtained by focusing the dispersed source on the specimen. ⺠We demonstrate improvement of information transfer in TEM to 0.5 Ã
