Abstract
An interferometer is often recognized as a lab instrument demanding environment-controlled rooms, skilled operators and enough space for the instrument. In the case of radius measurement of spherical and toric contact lenses we'll demonstrate the integration of such a typical "lab instrument" into modern production lines enabling 100% inspection. A modern LabVIEWTM interface for the instrument and intelligent alignment procedures allow the fully automated control of the samples under test. The paper will discuss the possibilities and solutions of automated interferometric measurements in general and its limits regarding the range of radius measurement and positioning in special. Interfaces between the interferometer, its software and the external controller are described.
