Abstract

1370198 Image intensifier tubes LICENTIA PATENT-VERWALTUNGS-GmbH 28 Feb 1972 [27 Feb 1971] 9120/72 Heading H1D An image intensifier tube having a photocathode 12 and a fluorescent screen 15 has a truncated cone accelerator electrode 6 on the external surface of which is mounted a truncated cone correcting ring 7. Another such ring, of greater diameter than the first, may also be mounted on electrode 6 between the first ring and screen 15, Fig. 2 (not shown). The angle between the wall of ring 7 and the tube axis is preferably 30 to 60 degrees. Further correction may be provided by a tubular electrode 3 having an inwardly projecting bead 9.
