We study the field that is produced by a paraxial refractive axicon lens. The results from geometrical optics, scalar wave optics, and electromagnetic diffraction theory are compared. In particular, the axial intensity, the on-axis effective wavelength, the transverse intensity, and the far-zone field are examined. A rigorous electromagnetic diffraction analysis shows that the state of polarization of the incident beam strongly affects the transverse intensity distribution, but not the intensity distribution in the far zone.
我们研究了傍轴折射轴棱锥透镜产生的场。比较了几何光学、标量波动光学和电磁衍射理论的结果。特别地，研究了轴向强度、轴上有效波长、横向强度和远场。严格的电磁衍射分析表明，入射光束的偏振态强烈影响横向强度分布，但不影响远场的强度分布。
