Cathode ray tube comprising a photoelectric cathode for converting a light image into an electronic image a field producing electrode and a screen for collecting the electrons characterized in that the field producing electrode and the collector screen are separated by a substantially null field space which has a smaller potential than the larger potential that takes place along the axis of the tube in the field between the photocathode and the field producing electrode.
