Abstract

A new type of machine setup combining a profilometer with a rotational measuring axis to measure aspheric lenses is presented. The instrument is very flexible, as it does not need a specific hologram for each type of asphere. In general, the setup is also capable to measure freeforms. Metrology strategies and first results are presented.
