Analysis of PSF of a Dipole Source by a High-NA Microscopy System

The emission light of a fluorescent molecule and the scattered light of a nanosphere are well modeled by dipole sources. Therefore, a dipole source is a good model for a point source which considers the vectorial effects in practice. Analysis of the PSF of such point source is important. The dipole source is built in VirtualLab Fusion. By connecting with a complex high-numerical-aperture microscopy system, the PSF is directly calculated in VirtualLab Fusion.
