46 Cluster Report Optics and Photonics – Optical Analytics PTB in Berlin Charlottenburg: the Imperial Metrology Institute was founded here in 1887 under Hermann von Helmholtz. © Physikalisch-Technische Bundesanstalt X-ray analytics X-ray fluorescence analysis (XRF) is a well-established method for measuring the concentration of individual elements in biological samples. For example, Bruker Nano GmbH offers a range of XRF devices which allow the quick metabolism testing of biological samples without having to prepare large samples. They provide valuable information on environmental influences. In addition, they are also used in building material analyses, geological investigations, and in forensics and archaeometry. In addition to X-ray analysis systems and components for element and structure analysis, Bruker Nano offers analysis systems for electron microscopes. These include energy dispersive X-ray spectrometers (EDS), wavelength dispersive X-ray spectrometers (WDS), electron backscatter diffraction systems (EBSD, Kikuchi diffraction), and micro X-ray sources for micro XRF at the SEM, as well as mobile and table-top micro XRF fluorescence (micro XRF) and total reflection XRF fluorescence spectrometers (TRFA). The Berlin-Adlershof Institute of Applied Photonics (IAP) e. V. is a non-profit, private industrial research institution working on projects in theoretical and applied research in X-ray physics and technology. Every two years it organises the Process-Oriented X-ray Analysis (PRORA). www.bruker.com/nano-analytics https://iap-adlershof.de/en/about-us-2/ The industry: market leaders and experts Over the years, the outstanding scientific infrastructure in Berlin and Brandenburg has favoured the founding and settlement of many companies. Some were able to develop into world market leaders in their segment in a very short time and have since then expanded this position or were able to develop further after being taken over by international corporations. Multi-element map of a fish fossil taken with the M4 TORNADO micro-RFA system by Bruker © Bruker Nano GmbH BESTEC GmbH has settled down in the direct vicinity of Bruker Nano at Berlin-Adlershof. BESTEC GmbH develops and manufactures optical systems for the soft and hard X-ray range which are used for synchrotron radiation sources, free-electron lasers, and laser plasma sources. These include monochromators, mirror and slit systems on the illumination side, as well as spectrometers, reflectometers, and ellipsometers in the field of experimental systems. www.bestec-berlin.de/

Cluster Report Optics and Photonics – Optical Analytics 47 The Berlin location of Helmut Fischer GmbH (formerly IfG Institute for Scientific Instruments GmbH) produces a wide range of X-ray capillary optics and micro- and nanostructured glass products at its Berlin-Adlershof location. It also offers X-ray sources (iMOXS) for such uses as X-ray diffractometry and X-ray fluorescence analysis, the latter being an additional component that can be installed on scanning electron microscopes. The X-ray fluorescence analysis is also used in measuring heads for monitoring processes such as the production of photovoltaic elements. www.helmut-fischer.de/en/germany Medical technology continues to be a major field of application for X-ray systems. Potsdam-based company TuR – Röntgentechnik GmbH offers various conventional and digital X-ray solutions for the use in X-ray therapy and diagnostics as well as solutions for special requirements. They also make special X-ray machines for veterinary medicine. www.tur-x-ray.com Analytics for Environmental and Life Sciences How clean is our water? What ozone levels can we expect this summer? Which contaminated sites have to be taken into account when redeveloping industrial wasteland? In order to answer such questions, environmental analysis deals with the qualitative and quantitative investigation of substances in the environment. Here, too, closely networked structures have emerged in Berlin and Brandenburg. Large, medium-sized, and small research institutes work closely together with a large number of mainly SMEs. High-resolution spectrometer and integrated sample system for the investigation of inelastic scattering processes on solid surfaces © BESTEC GmbH Element analyses at pressures far above the ultra-high vacuum are performed by systems produced by Specs GmbH. This makes it possible to examine liquids, tissue, plastics, or biomaterials in a turnkeyfacility with high throughput. From the insertion of the sample to the result it takes less than ten minutes. Specs also develops and produces systems for electron spectroscopy (XPS), electron microscopy at low energies (LEEM/PEEM), near-ambient pressure (NAP) XPS, and SPM (scanning probe microscopy) for the investigation of non-solid or degassing substances and in situ investigations of chemical surface reactions. www.specs.de In the Department of Analytical Chemistry, Reference Materials of the Federal Institute for Materials Research and Testing Bundesanstalt für Materialforschung und -prüfung (BAM), several units are addressing various aspects of environmental analysis. These include, for example, inorganic and organic trace analysis, environmental analysis, and chemical and optical sensors. The department also has special expertise in the analysis of inorganic trace element, element species, and isotopes, in particular of high-purity substances as well as environmentally relevant, biological, and medical materials. Moreover, the department is specialised in the development of suitable analysis processes and equipment. In the field of biophotonics, BAM is working on the development, application, and validation of optical-spectroscopic measuring methods for a wide range of liquid and solid samples, with a focus on static, time-resolved and spatially resolved fluorometry. The tasks include the characterisation of organic dyes, semiconductor quantum dots, and conversion materials; quantitative and absolute fluorescence measurements; as well as material and bioanalytical applications such as optical assays; and the development and provision of reference materials for optical spectroscopic analysis methods.
