Abstract
There is disclosed a phototube comprising a closed container having a light permeable face plate the outside surface of which is a light incident surface, a photocathode so provided in the closed container that at least a part of a photo-electric surface is inclined to the light incident surface, and an anode so provided in the closed container that an electron capturing surface is opposed to the photo-electric surface in parallelism therewith.
