Machine-integrated Ultra Precision Measurement of Functional Optical Surfaces

The quality inspection of optical parts, mould inserts for injection or precision glass moulding or microstructured surfaces is usually carried out on random samples under laboratory conditions outside the production process. Remachining or local corrections for the improvement of the products are difficult, since the part must be supplied back to further treatment. The exact relocation of the work piece in the machine with the demanded accuracies is rarely possible. Therefore the Fraunhofer IPT integrates ultra precise measuring technologies directly into the manufacturing machine.
