54 Cluster Report Optics and Photonics – Optical Analytics Certified testing of coating systems and surfaces The Surface Modification and Measurement Technology Department of the Federal Institute for Materials Research and Testing Bundesanstalt für Materialforschung und -prüfung (BAM) investigates thin layers and functional surfaces such as hard coatings (e.g. wear protection), optical coating systems (e.g. UV protection), and metallic coatings (e.g. corrosion protection or electromagnetic shielding). Many accredited test methods (DIN EN ISO/IEC 17025) are available for investigating the mechanical, optical, microstructural, and chemical characteristics of surface and layer parameters as well as general surface and layer properties such as surface topography and energy, layer thickness, and adhesion. www.berlinerglas.com www.bam.de/Navigation/EN/About-us/Organisation/Organisation-Chart/President/Department-6/Division-67/division67.html Nanotribology and nanostructuring of surfaces Analytical methods for tribology, mechanics, electrics, and optics on the submicrometre scale are the specialty of BAM’s Department of Nanotribology and Nanostructuring of Surfaces. Among other topics, the department is researching the structure-property relationships of complex polymer systems. Understanding the mechanisms of failure and damage in composites, inner and outer surfaces, and how polymer solids interface with organic, inorganic, and metallic solids is another focus of the department. www.bam.de/Navigation/EN/About-us/Organisation/Organisation-Chart/President/Department-6/Division-66/division66.html Optical coatings The Berliner Glas Group offers coatings for a wide range of substrates and for wavelengths from VUV to the IR range. Many years of experience with various types of coatings enable the development team to find the best possible solutions from coating design to serial production. Customer-specific development and coating tasks include: anti-reflective (AR) and mirror (HR) layers, polarising and non-polarising beam splitters, various filters (transmittance, edge, and laser protection filters), absorption layers, various mechanical wear protection layers (also DLC), as well as bondable and solderable layers.

Technology and knowledge transfer take place in research projects with industrial partners and through the training of highly qualified specialists. PVcomB offers support for industrial partners at the start of production or in the further development of industrial processes. It enables the research of promising new high-risk concepts and operates the transfer and upscaling of results from the theoretical research performed at HZB and TU Berlin up to the PVcomB standard size of 30 x 30 cm². Industrial partners can use the PVcomB reference lines as benchmarks, for example for new or alternative materials, analytics, and process controls. In a close collaboration between Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), Technische Universität Berlin (TUB), the University of Applied Sciences Berlin (HTW) and other partners, PVcomB educates qualified engineers and academics. www.helmholtz-berlin.de/projects/pvcomb/index_en.html

Cluster Report Optics and Photonics – Optical Analytics 55 Industrial Image Processing At PVcomB, thin-film photovoltaic technologies and products are developed jointly with the industry. © Berlin Partner for Business and Technology – Monique Wüstenhagen LEED imaging and measuring layer thickness in the EUV range Low-energy electron diffraction (LEED) can be used to study the arrangement of atoms on surfaces and in thin films. The material being investigated is illuminated with an electron beam. The electrons scattered on the sample surface are displayed on the monitor and create a characteristic diffraction pattern for the surface. This pattern provides information about the arrangement of the atoms and thus the composition of the sample. In the adjacent example image (LEED diffraction image), a sample was bombarded with electrons and the resulting diffraction pattern was recorded by the GE 1024 1024 BI MID camera from greateyes GmbH. The camera’s high sensitivity makes even weak diffraction reflections visible. Industrial image processing is used in almost every application imaginable. Today it is impossible to conceive of all sorts of production processes, as well as many testing and service areas, without it. The applications are correspondingly wide, ranging from agriculture to mechanical engineering, from the pharmaceutical industry to aerospace, to name but a few. Industrial image processing is a cornerstone of Industry 4.0, but there are also many prospects for research: the possibilities range from automated microscopic examination to the automatic acquisition and evaluation of aerial images. Industrial image processing technology is used to handle a wide range of tasks, including lighting, sensors, data transmission, and data processing. This Report reveals close ties to such topics as lighting and colorimetry (chapter 2.2 “Lighting Technology”), sensor technology (chapter 2.6 “Microsystems Technology”), but also to transmission technologies (chapter 2.3 “Photonics for Communications and Sensors”) and to various sensor topics described here. ISRA Vision Graphikon GmbH is based in Berlin-Adlershof. The company was integrated into ISRA Vision AG in 2010 to take advantage of growth opportunities in the solar market. Today, ISRA Vision AG in Darmstadt is one of the world’s leading companies in the machine vision sector. Among its most important applications are robot vision, surface vision, and quality inspection. www.greateyes.de/en www.isravision.com A relatively new company is 5micron GmbH. The current portfolio of 5micron GmbH is divided into two segments: surface measurement technology and special lighting systems. In the field of surface measurement, the company is developing projects based on optical methods primarily for the aerospace industry. The methods with resolutions in the micrometre range include deflectometry, the shadow-casting method, and pattern projection. The company’s work in special lighting systems concentrates on data transmission by light. www.5micron.de LEED diffraction image © greateyes GmbH
