  • Patent number: 4090758
    Abstract: The method comprises the steps of providing a camera tube having an evacuated envelope, a photoconductive layer primarily of lead monoxide, an activated getter and an unactivated getter within the envelope. After a period of operation or storage the tube exhibits a deterioration in spectral photosensitivity of the layer. The characteristic ratio of blue light photosensitivity is measured and when the ratio is less than about 80% the unactivated getter is activated to regenerate the tube.
