MINFLUX has achieved extraordinary resolution in superresolution imaging and single fluorophore *** is based on localizing single fluorophores by rapid probing with a patterned beam that features a local intensity *** implementations,however,are complex and expensive and are limited in speed and ***,we show that a combination of an electro-optical modulator with a segmented birefringent element such as a spatial light modulator produces a variable phase plate for which the phase can be scanned on the MHz *** or top-hat phase patterns generate high-contrast compact excitation point-spread functions for MINFLUX localization in the x,y,and z-direction,respectively,which can be scanned across a fluorophore within a microsecond,switched within 60 microseconds and alternated among different excitation *** discuss how to compensate for non-optimal performance of the components and present a robust 3D and multi-color MINFLUX excitation module,which we envision as an integral component of a high-performance and cost-effective open-source MINFLUX.
