When two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61l/NA

Formally, the … WebCircular Aperture Diffraction. For monochromatic light of wavelength λ = nm. incident upon a circular aperture of diameter d = micrometers, d = x 10^ m, and projected on a screen at distance D = m, the displacement from the centerline on the screen is given by the relationship. Displacement y = Screen distance D*m value* wavelength / aperture ...

When a point source, such as a star, is examined using a circular aperture telescope, the image is a disc encircled by a number of very faint rings, rather than a point source.
