Abstract
A neutralization device includes a light emitter, an optical conductor and multiple diffusion portions. The light emitter emits light for neutralizing an object. The optical conductor, which is opposed to the object and extends in a longitudinal direction, directs and applies the light to the object. The diffusion portions are arranged on the optical conductor in a zig-zag manner from one end of the optical conductor to the other and diffuse the light.
Claims17
A neutralization device comprising:
- a light emitter configured to emit light that neutralizes an object;
- a longitudinally extending optical conductor opposed to the object and configured to direct and apply the light to the object, the optical conductor being substantially columnar in a longitudinal direction;
- and
- a plurality of diffusion portions disposed on the optical conductor in a zig-zag manner from one end of the optical conductor to the other, and configured to diffuse the light;
- wherein the optical conductor includes a first end face substantially perpendicular to the longitudinal direction and a second end face opposite to the first end face, the first end face being configured to face the light emitter so as to receive the light emitted by the light emitter;
- and
- wherein the first end face, the second end face, and a portion of the optical conductor at which the diffusion portions are formed respectively have first, second, and third diameters, the first diameter being larger than the second and third diameters.

A neutralization device comprising:
- a light emitter configured to emit light that neutralizes an object;
- a longitudinally extending optical conductor opposed to the object and configured to direct and apply the light to the object, the optical conductor being substantially columnar in a longitudinal direction;
- and
- a plurality of diffusion portions disposed on the optical conductor on a plurality of parallel lines that extend in the longitudinal direction of the optical conductor, and configured to diffuse the light, the lines including a first line and a second line adjacent thereto, the diffusion portions including a plurality of first diffusion portions disposed on the first line and a plurality of second diffusion portions disposed on the second line, each first diffusion portion being adjacent to at least one of the second diffusion portions, each first diffusion portion having a center point that is separated in the longitudinal direction from a center point of each second diffusion portion that is adjacent thereto;
- wherein the optical conductor includes a first end face substantially perpendicular to the longitudinal direction and a second end face opposite to the first end face, the first end face being configured to face the light emitter so as to receive the light emitted by the light emitter;
