Derivation of abbe diffraction limit
Webwavelength of light, the smaller its angle of diffraction for a given slit width. Thus shorter wavelengths give better resolution, and this is taken into account in Abbe’s formula for resolution. Resolution Based on his work with diffraction from a line grating, Abbe devised an equation for the resolving power of the microscope: D = lambda / 2 NA WebDiffraction limit means that an imaging lens could not resolve two adjacents objects located closer than λ/2NA , where λ is the wavelength of light and NA is the numerical …

The Abbe diffraction limit for a microscope The observation of sub-wavelength structures with microscopes is difficult because of the Abbe diffraction limit. Ernst Abbe found in 1873 that light with wavelength $${\displaystyle \lambda }$$, traveling in a medium with refractive index $${\displaystyle n}$$ and … See more The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. However, there is a principal limit to the resolution of any optical system, … See more There are techniques for producing images that appear to have higher resolution than allowed by simple use of diffraction-limited optics.
