Tight Focusing of Variously Polarized Beams by an Idealized Aplanatic Lens
Abstract
Knowing the vectorial electric field distribution near the focus of a high-NA objective lens is of great importance for applications e.g. microscopy, optical tweezer, laser machining, etc. The used high-NA objective lens is often assumed as an aplanatic lens (means spherical aberration and coma are neglected). We demonstrate the focusing of variously polarized beams, e.g. linearly, circularly and radially polarized beams, by an idealized aplanatic lens in VirtualLab Fusion. Further, the focal field with respect to different shapes of apertures, e.g. circular and annular, is investigated.
