Abstract

1413908 Image intensifier tubes LITTON INDUSTRIES Inc 29 May 1973 51513/74 Divided out of 1413907 Heading H1D The Specification is similar to that of the parent, except that the particular description indicates that the electron and ion trapping film 15 may also be of metal, and the claims specify that that film is substantially lighttransmissive over the visible range of the spectrum, whereby to avoid reflection to the photocathode of that small percentage of incident light which passes through the latter due to its imperfect opacity.
