ABSTRACT:
Methods are disclosed for manufacturing an electrostatic deflector comprising multiple electrodes. The electrostatic deflector is of a type not tending to generate large eddy currents during use. The electrodes are arranged as electrode-members relative to each other in a desired angular relationship with high precision around an optical axis. Each electrode is formed by adhering a conductive film to portions of the surface of an insulative electrode-member material except an outer surface of the electrode-member, and a conductive film is adhered to at least some of the inner surface of an insulating outer casing. The electrode-members are inserted into respective grooves in a jig; then the outer surface of each electrode-member is attached to the inner surface of the outer casing. Lead wires can be attached to the electrodes, and the jig is removed by dissolution or melting.
