A zone plate consists of a set of radially symmetric rings, known as Fresnel zones, which alternate between opaque and transparent. Light hitting the zone plate will diffract around the opaque zones. Very similar to pinhole photography using a zone plate creates a soft focus with a halo glow around objects.
