An increasingly more compact and favorable system design is demanded on optical systems such as zoom lenses, optics for DVD drives and lenses in the cameras of mobile phones, for example.

For this purpose, in addition to classic, spherical lense shapes (sphere-shaped), the optics industry is increasingly producing aspheric shaped (not sphere-shaped) lenses.

The evaluation program serves to analyze measurements on spherical surfaces with Mahr contour measuring units. Measured profiles are imported, the nominal form of the aspheres are defined and
the residual error is determined compared to the nominal form. The data is made available for readjustment of the processing machines (closed loop).

In comparison to the laser interferometer, the tactile measuring technology also allows 2D and 3D measurement of optically rough surfaces, so that testing and correction is possible already early on
in the production process (grinding).
