electron optics n. [in sense (a) after German Elektronenoptik (A. Heydeweiller 1915, in Verhandl. der Deutsch.

1916 Chem. Abstr. 10 299 The number of these latter electrons is not definitely known, but is almost surely greater than 1, from considerations of the electron-optics of the H-cation in H₂O.

1932 Sci. Abstr. A. 35 645 Application of geometric electron optics makes it possible to explain the behaviour of the beam in an electron tube.

1969 Times 28 Mar. 25/3 The British company claims to have gained the lead, with some Government financial aid, through its expertise in precision and electron optics.

1990 Proc. Royal Microsc. Soc. 25 339/3 (advt.) Optimum conditions for a contamination-free specimen environment and maximum cleanliness of the electron optics.

2007 Ultramicroscopy 107 174/1 One can presuppose that the magnitude of lens errors in electron optics is very small.
