WebAiry Patterns and the Rayleigh Criterion - Java Tutorial. Airy diffraction pattern sizes and their corresponding radial intensity distribution functions are sensitive to the combination of objective and condenser numerical apertures as well as the wavelength of illuminating light (when monochromatic light is used to illuminate the specimen). 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.
