SUMMARY
The axial resolution in optical microscopy is defined by the equation r(z) = 2π / (NA)^2, where NA represents the numerical aperture. This resolution limit is derived from Rayleigh's limit, as detailed in Born and Wolf's "Principles of Optics," 7th edition, specifically in section 8.8. The discussion highlights the challenge of deriving this equation using numerical methods, particularly when evaluating the diffraction integral on-axis. Understanding these concepts is crucial for advancing optical microscopy techniques.
