Abstract
PURPOSE: To improve the uniformity of not only a central modulation degree but also a peripheral modulation degree, by mounting coils or magnets for generating magnetic fields correcting the distortion of the shape of electron beams in addition to the compensation of the alignment of a camera tube.
CONSTITUTION: Alignment magnets 14 and magnets 15 for correcting the distortion of beams are installed to an electrostatic focusing type camera tube 1. Said alignment magnets 14 consist of magnets that are two-poles magnetized, and the intensity and direction of magnetic fields are adjusted by stacking the two magnets and by regulating the angles. The magnets 15 for correcting the distortion of beams are ring-shaped and are composed of magnets that are four-poles magnetized around a shaft, and the angles are adjusted by stacking the two magnets. Thus, the uniformity of not only a central modulation degree but also a peripheral modulation degree is improved because the distortion of the shape of electron beams can be compensated by adding the correction of alignment, and the color shading of the pictures of a frequency separation system color camera tube can be bettered.
