ABSTRACT:
The invention is directed to an electron energy filter which is assembled from three or four plates placed together in a sandwich-like configuration. The pole pieces are seated on the inner sides of the outer plates and attached thereto. The pole pieces can therefore be produced in pairs so that their outer surfaces match precisely. This assembly is economical and provides a precise manufacture.
