The master moulds for manufacturing the moulds for contact lens production must be tested. The lenses themselves must also be measured. The surface shape deviation of the lenses and tools is important. Due to the low tolerances of a few micrometres, the requirements for measurement uncertainty are very high, while the requirement for measurement time is secondary. The highly reflective tool surfaces pose a special challenge for optical measurements.
