    Abstract: The invention concerns a manufacturing process of a photocathode for an image intensifier tube.According to this process, the photocathode is made within the tube by depositing a photoelectric material on a conductive substrate by vacuum evaporation. During this operation, the optical transparency of the deposit is checked by illumination of this deposit by a light source. According to the invention, this light source is located within the tube and is protected from the vapors of the photoelectric material. In the prior art, this light source was located outside the tube and the illumination of the deposit was not sufficient.The invention has applications in the field of image intensifier tubes.

    Abstract translation: 本发明涉及一种用于图像增强管的光电阴极的制造方法。 根据该方法,通过真空蒸发在导电性基板上沉积光电材料,在管内形成光电阴极。 在该操作期间,通过用光源照射该沉积物来检查沉积物的光学透明度。 根据本发明,该光源位于管内并被保护以避免光电材料的蒸气。 在现有技术中,该光源位于管外部,并且沉积物的照射不充分。 本发明在图像增强管领域具有应用。
