Abstract
A radial or tangential polarization of a beam of light radiation with respect to an optical axis, along which said beam propagates, is effected by causing interaction of the beam with at least one conical interface between a pair of optical media having different indices of refraction. The conical interface(s) may be provided with a polarization-selective coating.
