Abstract

We propose a localized surface plasmon microscope that provides simultaneous imaging of refractive index and fluorescent intensity distributions. We show experimental images of fluorescent and transparent particles under circular pupil illumination to confirm simultaneous high-resolution imaging. Furthermore, we investigate applicability of annular pupil illumination employing two axicons to improve energy efficiency in the fluorescent imaging and find that a brighter image is obtainable by maintaining high spatial resolution for both imaging modes.
