Abstract

1,057,684. Electron microscopes. PHILIPS ELECTRONICS AND PHARMACEUTICAL INDUSTRIES CORPORATION. July 5, 1963 [July 5, 1962], No. 26757/63. Heading H1D. An electron microscope object-diaphragm comprises two parallel electrically conductive limbs carrying a resistive, electrically heated, diaphragm in the form of a flat plate with a central aperture for the passage'of the electron beam, the passage being conical in section and expanding along the beam so that electrons of the beam do not strike the walls of the aperture.
