摘要： PURPOSE:To obtain beam spots of about a constant diameter over the whole range from low brightness to high brightness by arranging control electrodes G2-G4 and giving the specific potential inclination between the electrodes G2 and G3 while giving the potential which takes the maximum value in the region of the electrode G3 and the minimum value in the region of the electrode G4. CONSTITUTION:From the side of G1 electrode 2 acting as a control electrode to the side of G5 electrode 21 acting as the last acceleration electrode, G2 electrode 3, G3 electrode 22 and G4 electrode 23 are arranged in order. The electrode 3 has the same structure as the acceleration electrode and the plate-shaped electrode 22 adjacent to the electrode 3 is adjacently arranged so as to have the potential inclination of 10 -5X10 V/cm to the electrode 3. The electrodes 23 and 21 are cylindrically formed, the electrode 22 is given a constant potential Vg3 not exceeding 10KV, the electrode 23 is given a variable focusing potential Vfoc lower than the potential Vg3 while the electrode 21 is given high potential of about 30KV. Consequently, the thick main lens 25 is substantially generated by participation of the electrodes 22, 23 and 21 so as to obtain beam spots having about a constant diameter over the whole range from low brightness to high brightness.

摘要： PURPOSE: To improve the resolution at the periphery without deteriorating that of the screen center by forming the first non-rotation symmetric lens with a pre- focus lens section and the second one with a main lens section and constituting so that the first and second non-rotation symmetrical lenses are at a right angle to each other.
CONSTITUTION: When the first non-rotation symmetric lens 37 and the second non-rotation symmetric lens 36 are combined together, a nearly circular luminescent spot can be obtained due to their consolidated action, but the focusing action of the first non-rotation symmetric lens is stronger in the vertical axis direction, thus the incident position to the second non-rotation symmetric lens in the vertical axis direction is nearer to the center axis than that of the horizontal axis, thereby the spherical aberration applied from the second non- rotation symmetric lens is small. Therefore, when a beam is applied the deflection aberration, the oblong halo generated at diagonal sections of the screen can be made small and the resolution is improved.

摘要翻译：目的：通过用预聚焦透镜部分形成第一非旋转对称透镜并且第二非旋转对称透镜具有主透镜部分并且构成使得第一和第二非透镜部分的第一和第二非透镜部分旋转对称透镜彼此成直角。构成：当将第一非旋转对称透镜37和第二非旋转对称透镜36组合在一起时，由于其固定的作用，可以获得近似圆形的发光点，而是第一非旋转对称透镜36的聚焦作用在垂直轴方向上较强，因此，垂直轴方向的第二非旋转对称透镜的入射位置比水平轴更靠近中心轴，由此从第二非旋转对称透镜施加的球面像差镜头很小因此，当施加光束的偏转像差时，可以使在屏幕的对角线部分处产生的长圆晕变小，并且提高分辨率。
