Focusing of Cylindrical Vector Beams by a High-NA Objective Lens

The cylindrical vector beams are studied intensively in recent years. The small focal spot can be obtained by radially polarized beam for high-resolution applications. A donut-shaped focal spot can be obtained by azimuthally polarized beam, which has the potential for advanced imaging and lithography. In VirtualLab Fusion, the focusing of such cylindrical vector beams can be modeled and analyzed straightforwardly. The focal spot is demonstrated and analyzed in a fully vectorial manner.
