    摘要： A limiting aperture (44) disposed in a relatively low voltage and electrostatic field-free region in the main focusing lens portion of an electron gun (30) in a cathode ray tube (CRT) provides reduced electron beam spot size and improved video image contrast and purity in the CRT's display screen (42). The generally circular limiting aperture is disposed on the axis (A') of the electron gun (30) and within a charged electrode (G4), or grid, within the main focusing lens. The cylindrically shaped, charged grid is elongated along the gun axis (A') and includes generally circular recesses (52, 54) in facing surfaces thereof, which recesses are also disposed on the gun axis (A') and separated by an inner partition (56) defining the limiting aperture (44). The charged grid is maintained at a voltage VG, with VG
