High quality lenses have reached a standarad where wavefront tolerances of a few nanometers for transmission and surface figure of individual components are necessary. The standard measuring tool in production is digital interferometry. To satisfy the demands of current and future production quality interferometruc equipment has to provide an overall accuracy below one nanometer under fabrication environment. This is reasonable, especially if "work man's rule" is applied demanding a tolerance/accuracy factor for metrology of ≥10:1. In this paper the limitations on interferometry for material and surface inspection as well as possible improvements are discussed.
