In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped ...

High precision, dynamic interferometer combines short and long coherence capabilities into one system for measuring an expanded range of optics. The AccuFiz Duo Fizeau interferometer combines short ...

This release is also available in German. Due to their stable design, Fizeau interferometers are used to determine the topography of surfaces such as, e.g., plane surfaces. PTB has now developed a ...
