摘要

Radially polarized beams have cylindrically symmetric polarization profile. When focused tightly such beam gives rise to a strong axially polarized electric field component at the focus. Owing to this unique property, radially polarized beams have found applications in a number of important areas. There has been published research work on the properties of radially polarized beam in the presence of primary monochromatic aberrations. However optical system involving such beam may also contain secondary or higher order aberrations. Unfortunately there has not been much study in the available literature in this regard. In this paper we will employ vectorial diffraction theory to investigate the effect on focal field components due to the presence of second order aberrations.
