PURPOSE: A near field scanning optical microscope is provided to access to an electric field or a magnetic field by using a single probe. CONSTITUTION: A near field scanning optical microscope(1) includes a probe unit(10), a grid unit(20) and a light source unit(30). The probe unit is in the form of a cone. The grid unit is carved in the probe unit. The light source unit is transmitted to both sides of the probe unit. When light in the light source unit is transmitted to the grid unit, surface plasmon is generated. The surface plasmon is propagated to the vertex in the probe unit. |
