title: Testing of aspherical surfaces with newton fringes.
abstract: The shape of any aspherical surface with rotational symmetry can be very easily found with great accuracy using Newton fringes formed against a spherical test plate.To make it possible, a special mathematical procedure is devised for use with a special measuring system here described.
