    摘要： The focussing devices of the invention comprise a metal electrode (6) assembled in the envelope (10) through which the electron beam being focussed propagates, said assembly being realised by means of a fixing system comprising a flexible skirt (11) attached around the envelope, and rigid insulating components rigidly attached on the one hand to the electrode (6) and on the other to the skirt (11).

    摘要： A minifying image tube, such as an X-ray converter or image intensifier tube, is disclosed employing a curved photocathode for converting a photon image into an electron image. A flat image converter screen is provided for converting the minified electron image into an optical output image. An electrode structure is disposed between the photocathode and the flat converter screen for accelerating and focusing the electron image upon the converter screen. The electrode structure includes a plurality of coaxially aligned axially spaced cylindrical electrodes of decreasing diameter taken in the direction from the photoemitter toward the converter screen. The final or anode electrode projects into a constricted electron exit aperture in the next preceding electrode structure in order to shape the equipotentials at the entrance of the anode such as to obtain uniform resolution of the electrode image focused upon the flat converter screen over substantially the entire area of the converter screen.

    摘要： In a cathode ray tube of the single-gun, plural-beam type in which the plurality of beams are made to intersect each other at a location in the tube between the beam producing means and the screen, a focusing lens for focusing all of the beams on the screen is made up of a plurality of lens components arranged in axial succession and defining an optical center of the focusing lens disposed within the latter, and such focusing lens is positioned so that the optical center thereof is substantially at the location where the beams intersect. The lens components of the focusing lens may be symmetrical or asymmetrical with respect to the optical center, and in the latter case may be effective to compensate for any optical aberrations imparted to certain of the beams when the latter are converged to intersect by means of an auxiliary lens.
