Abstract

Accurate electromechanical gauging of steep aspheric profiles is often complicated by the complexity of the relationship between the locus of the probe tip center of curvature and the probe tip/asphere contact point. Solving for the contact point is usually done in an iterative manner, which is a fairly laborious computing chore. But since a considerable amount of sag information is conventionally produced by the lens design program generating the aspheric surface, it is possible to shortcut the process by using these data to solve directly for the probe tip coordinates as a function of the aspheric prescription.
