    "abstract": "We use fluorescent nanospheres as scalar detectors for the electric-field\nintensity in order to probe the near-field of an optical tip used in\naperture-type near-field scanning optical microscopy (NSOM). Surprisingly, the\nrecorded fluorescence images show two intensity lobes if the sphere diameter is\nsmaller that the aperture diameter, as expected only in the case of vector\ndetectors like single molecules. We present a simple but realistic, analytical\nmodel for the electric field created by light emitted by a NSOM tip which is\nquantitative agreement with the experimental data.",
