Paper Abstract

The production process of aspheric lenses relies on the measurement results from interferometers and profilometers. A new type of machine setup combining a profilometer with a rotational measuring axis is presented. It allows to measure lenses in all production stages, i.e. from rough grinded surfaces, which can not be measured with interferometers up to polished surfaces. The setup is very flexible, as it does not need a specific hologram for each type of asphere. These properties provide new options to optimize the production process.
