Project: Optical and tactile metrology for absolute form characterisation

Measurement of the full 3D form of optical curved surfaces is important for characterising surfaces used in the optics and precision engineering industries, as well as in astronomy and science. Currently, two types of measurements are used: imaging or single point scanning - both of which have advantages and disadvantages that limit manufacturing capability. The absolute form measurement of optical components - ranging from flat surfaces to aspheres and free form surfaces - was significantly improved by this project, through the development of improved measurement techniques, tools and standards. Tactile, optical and capacitive methods, marker production and mathematical methods were all further developed. The project strengthens Europe’s position in the global photonics market and will lead to better optical components and systems, which can be manufactured with less energy and waste.
