A dual-color super-resolution microscope with polarization and orientation-resolving capabilities is presented. Combining single-molecule localization methods with simultaneous polarization measurements enables the determination of the orientation of single emitters, such as quantum dot nanocrystals, with sub-10 nm precision. Additional simultaneous spectral characterization of particle emission allows the capture of multiple optical properties that impact energy transfer. We report on the instrumentation development and the results from coupled quantum dot clusters.
