(a) Normalized radial distribution of the light intensity within the spots created by Fresnel zone plates with a given number of transparent zones (symbols) and by refractive lenses of the same aperture and focal length (solid lines). (b) The radius at half of the maximum intensity of the spot created by a zone plate as a function of the number of zones.
