Abstract

1420803 Electron microscope lenses ASSOCIATED ELECTRICAL INDUSTRIES Ltd 26 June 1974 [28 June 1973] 30764/73 Heading H1D In a transmission electron microscope and X- ray probe analyser the electrons diverging from the image of the tungsten filament thermionic cathode formed by a first condenser lens (11, Fig. 1, not shown) enter from above and are focused on to a sample on support 33, forming an image of the filament source 100 nm in size, by means of the gap field in the upper part of combined second condenser and objective lens 12. Each part comprises a gapped iron magnetic circuit 23, 29 or 24, 30 having annular symmetry and surrounding an energizing winding 31 or 32, the currents being independently adjustable and the radial fields produced in dished iron plate 25 tending to cancel. The condenser component 23 holds four pairs of deflector coils 37 (only two shown) for adjustment of the beam position or for scanning. X-rays emitted by the electron irradiated area of the sample in holder 33 within the lower gap produce a signal from detector 38, its siting in direct line from the sample necessitating enlargement of hole 26. In an alternative embodiment hole 26 is reduced, the X-rays emerging through oblique holes 39 arranged symmetrically, one or more pointing at detector or detectors 38.
