Abstract

A deflection unit for color television picture tubes where the beam generating systems or electron guns that are required to generate the individual color components are spatially located and separated from each other, preferably in a line, in where the deflection unit generates an electromagnetic deflection field and is located outside the neck of the imaging tube; color television, and the two fields of deflection of the electron beam that extend vertically relative to the axis of the tube, are generated by two deflection coils that are independent of each other. Characterized in that the ferro-magnetic elements (21, 22, 31, 32, 33, 34) are inserted in the distribution of the magnetic field in front and/or behind the deflection unit (10, 11), because the ferro elements -magnetics are located symmetrically in relation to the longitudinal axis (z) of the deflection unit and symmetrically in relation to the associated main deflection axis (x, y -u horizontal-vertical-axis), and because at least those elements that belong to one of the main deflection axes (21, 22 or 31, 32, 33, 34) they are located in a plane that extends vertically in relation to the longitudinal axis (z) of the deflection unit.
