Description
Summary:Optical coherence tomography is used to measure the thickness and uniformity of individual thin layers in real time during LI production run. Besides achieving significantly higher process security, the Fraunhofer researchers say that this OCT-enabled control technique should save material supplies amounting to euro100,000 (US$143,000), even when deployed in a medium-capacity production facility.
