The assembly of bundled optical fibers with plug connections, which are used in information and communication technology, is still difficult to automate today: Fibers with fixed polarization must be aligned with great precision in the connector, and their handling and bonding also require maximum accuracy. Together with the Dutch University of Twente and the industrial partners Aixemtec GmbH from Herzogenrath and Phix B.V. from Enschede, the Fraunhofer Institute for Production Technology IPT from Aachen presented a modular system for the automated assembly of polarization-maintaining fiber arrays at the "Laser – World of Photonics" trade fair from 24 to 27 June 2019 in Munich.
With so-called single-mode fiber arrays, the precise arrangement of the individual fibers is crucial.02.07.2019 | Read more
To guarantee high quality pharmaceuticals, manufacturers need not only to control the purity and concentration of their own products, but also those of their suppliers. Researchers at the Fraunhofer Institute for Applied Solid State Physics IAF have developed a measuring system capable of identifying a wide variety of chemical and pharmaceutical substances remotely and in real time. It is perfect for the use in the pharmaceutical, chemical and food industry.
Especially for pharmaceutical and food productions a continuous control of ingredients is indispensable. Usually, this would be done by a sampling and a...24.06.2019 | Read more
The wax injection molding process is used to produce models for investment casting quickly and easily. For a non-destructive demolding of the wax parts, silicone-based release agents have had to be used until now, which come along with considerable disadvantages for man and product. In an AiF-funded project, developers at Fraunhofer IFAM have succeeded in developing a release agent-free release layer system that provides a sustainable permanent coating on the tool. The so-called ReleasePLAS® technology offers both technical and economic advantages and will be presented at GIFA 2019 (Hall 13, Booth A34).
The investment casting process is used when filigree structures or particularly high-quality surfaces are required for the cast component being produced. The...21.06.2019 | Read more
From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components.

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...19.06.2019 | Read more
Within the framework of quality monitoring of lightweight construction components intelligent sensor systems become crucial: In many industries, especially in aerospace engineering and automotive industry, the use of forward-looking hybrid designs based on fiber composites and light metals is steadily rising. From 25-29 June 2019, at the 14th International Foundry Trade Fair in Düsseldorf, Fraunhofer IZFP scientists will introduce a robot-assisted sensor system for the nondestructive inspection of hybrid cast components, which can easily be integrated into the quality monitoring of production processes (hall 13, booth A34).
Time-consuming destructive inspection methods used in quality assurance result in enormous costs, as the product is damaged or even destroyed during the...13.06.2019 | Read more
For the functionality of optical systems, the geometrical shape of the functional optical surfaces and their position relative to each other is a decisive criterium. However, small-aperture polymer optics, which are in great demand, for example, in mobile phone cameras, endoscopes or car sensors, cannot yet be checked with sufficient accuracy using standard metrological methods. At the LASER - World of Photonics trade fair from 24 to 27 June 2019 in Munich, the Fraunhofer Institute for Production Technology IPT from Aachen, Germany, will present a new tomographic method that can measure such optical components with a small aperture non-destructively and in one step.
The new method is based on optical coherence tomography (OCT) and can capture both functional surfaces of an optical system simultaneously in one single scan.12.06.2019 | Read more
Making innovations a reality - at the LASER World of Photonics in Munich from June 24th to 27th, 2019, the Laser Zentrum Hannover e.V.

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.
In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...
