WebWhen light passes through an aperture with diameter D, then diffraction limits the resolution to θ = 1.22λ/D. If the angular separation of two sources is less than θ, they cannot be resolved. The closer you are to two objects, the greater is the angular separation between them. Up close, two objects are easily resolved. WebDec 20, 2024 · Rayleigh and Dawes resolution.

"WebAbbe’s diffraction formula for axial (i.e. Z) resolution is: d= 2 λ/NA2. Again, if we assume a wavelength of 514 nm to observe a specimen with an objective of NA value of 1.45, then the axial resolution will be 488 nm. The Rayleigh Criterion is a slightly refined formula based on Abbe’s diffraction limits: R= 1.22 λ/NA obj + NA cond " - Rayleigh resolution formula
