(TU Delft ImPhys/Optics) Pereira, S.F. (TU Delft ImPhys/Optics) Urbach, Paul (TU Delft ImPhys/Optics) Date 2018 Abstract Rigorous vectorial focusing theory is used to study the imaging of small adjacent particles with a confocal laser scanning system. We consider radially polarized illumination with an optimized amplitude distribution and an annular lens to obtain a narrower distribution of the longitudinal component of the field in focus. A polarization convertor at the detector side is added to transform radial polarization to linear polarization in order to make the signal detectable with a single mode fiber.
