PHOTOELECTRIC TUBE

Japanese Patent JP3899197

B2

PROBLEM TO BE SOLVED: To obtain a sufficient linearity characteristics and a sufficient angle characteristic dependent on COSθ, and to aim cost reduction.
SOLUTION: This photoelectric tube has such a formation that a photoelectric surface is arranged adjacently to a light incident face plate 2, and that an arrival rate of the light entering the light incident face plate 2 obliquely on the photoelectric surface 5 is improved compared with a conventional way in which the photoelectric surface 5 is separated from the light incident face plate 2, and such a formation that, in addition to a translucent conductive film 9 installed prescribedly on the light outlet face of the light incident face plate 2, a photo-electron collecting electrode 10 is installed close at least to the translucent conductive film 9 between the light outlet face of the light incident face plate 2 and the translucent conductive film 9, and that the photo-electron collecting electrode 10 is made to also have an anode potential, namely, the translucent conductive film 9 and the photo-electron collecting electrode 10 are made to have the same potential, to thereby enable to collect excellently photo-electrons from the photoelectric surface 5 on both the translucent conductive film 9 and the photo-electron collecting electrode 10, and additionally such a formation that the formation of wiring or the like is simplified by making the translucent conductive film 9 and the photo-electron collecting electrode 10 have the same anode potential as the potential of conductive containers 1, 3.
