High-resolution microscopy without high-numerical-aperture lenses: standing-wave scanning fluorescence microscopy


We propose and demonstrate a new type of far-field fluorescence microscope capable of sub-λ resolution without high numerical aperture (NA) lenses. In the new standing-wave scanning fluorescence microscope, focused illumination is generated by the interference of a large number of planar wavefronts. Scanning confocal detection eliminates the need for… (More)
