Abstract

By specializing to the problem of axial imaging by surfaces with rotational symmetry a complete wavefront analysis is possible. Applications to multifocal lenses are given.

A wavefront analysis using elementary methods is possible for the case of axial imaging by an arbitrary rotationally symmetrical surface. Optically this approximates an eye fitted with a centered multifocal simultaneous vision contact lens. The essential assumption is that paraxial optics holds at each surface except one surface of the contact lens.
