Compared with the traditional imaging technique, Fourier microscope can directly observe the spatial frequency distribution. Therefore, it is widely used today for example: surface plasma observation, photonic crystal imaging and so on. With VirtualLab Fusion, complete Fourier microscope systems can be modeled and used for monolayer imaging. Specifically, we demonstrate the influence of several physical optical effects, including Fresnel loss and lens aperture diffraction at each optical interface.

Modeling a complete high NA Fourier microscope system for monomolecular imaging, specifically showing examples such as Fresnel loss, diffraction due to aperture, and comparing simulation results with reference values.

High NA objective lens is widely used in optical lithography, microscopy and so on. It is very important to consider the vector properties of light in focusing simulation.
