WebWhen two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61λ/NA. In cases where two adjacent Airy patterns become closer to each other than in the Rayleigh criterion, the separation is known as the Sparrow limit, which is given by the equation: D = 0.47λ/NA WebRayleigh's Criterion is usually applied to circular apertures, where the criterion for resolution is when the center of one Airy disk pattern falls on the first minimum of the Airy disk pattern of the second source. The angular separation θ is then. θ = ( 1.22 λ ) / D. where λ is the wavelength of light, and D the aperture diameter.
