Abstract
An azimuthally polarized beam when passes through a helical phase mask, gives rise to a circularly symmetric focal spot which appears very similar to the focal spot of normal linearly polarized beam with a plane wavefront. However it is noticed that common monochromatic aberrations have different degree of influence on the two types of beams, that is the azimuthally polarized beam with a helical phase mask and linearly polarized beam with a plane wavefront. In this paper we present a detailed investigation on the effect of primary aberrations on the two types of vector beams.
