Webb31 mars 2024 · Therefore, any technique deploying the wavelength-based image formation must obey the Abbe diffraction limit; hence, visible light and/or UV light cannot image the atomic lattice. Scientists had thought that if one could overcome this physical barrier of the Abbe diffraction limit, then imaging the lattice with a larger wavelength could have been … WebbConsidering green light around 500 nm and a NA of 1, the Abbe limit is roughly = = (0.25 μm), which is small compared to most biological cells (1 μm to 100 μm), but large …
