Abstract

The use of radially polarized light is known to produce, when focused by a high numerical aperture objective lens, a spot of light whose polarization is predominantly axial. We have generated radially polarized beams accurately and have confirmed this behavior experimentally and have also shown that the axial polarization leads to a ring type image of sub-resolution gold beads.
