- Haidinger fringe
Haidinger fringes are
interference fringe s formed by theinterference of monochromatic andcoherent light to form visible dark and bright fringes. Fringe localization is the region of space where fringes with reasonably good contrast are observed.Haidinger fringes are fringes localized at
infinity . Also known as fringes of equal inclination, these fringes result when light from anextended source falls on a thin film made of an optically denser medium. They are also observed in Fabry-Pérot andMichelson interferometer s. They can be observed by introducing aconverging lens between the film and observation plane with focus of the lens lying in observation plane.ee also
