School laboratories network – “GenaU”
Eleven student laboratories at research facilities and universities in Berlin and Brandenburg have come together under the slogan “Together for Scientific-Technical Instruction” (In German: GenaU). The main sponsor of the GenaU network is the TSB Technology Foundation Berlin, which is committed to the support and training of young talent in scientific and technical careers (

GenaU is also supported by the Robert Bosch Foundation and LeLa - Center for Consulting and Quality Development. There are more student laboratories, and with a greater diversity, in the Berlin-Brandenburg region than anywhere else in Germany. The GenaU network can offer instruction in science and engineering for every age group and type of school.

Generating enthusiasm for science and technology is the main aim of the student laboratories. Furthermore, for gifted students and students with a particular interest in science, the laboratories can offer numerous opportunities for a more far-reaching involvement with science and/or technology. Such activities make an important contribution to attracting new young talent and providing them with the necessary qualifications. Over 20,000 students perform experiments in the network’s labs each year. Around 800 accredited teachers receive advanced training in the labs and approx. 200 who are studying for a teaching certificate obtain practical training in the student laboratories.

What you can see at the Optics Workshop in Hall 18, Stand 207:

- The DLR_School_Lab Berlin-Adlershof of the German Aerospace Center will show a model of a High Resolution Stereo Camera (HRSC). One of the components of the Mars Express mission, this camera has been delivering images from the surface of Mars since 2003. In addition, visitors can use a thermal imaging camera to take pictures of events at the fair.

- The MicroLAB of the Ferdinand-Braun-Institute for High Frequency Technology will show examples of fine structures, chips and wafers, as well as ways in which these can be created by students themselves in the laboratory.

- The PhysLab of Berlin’s Free University invites students to build a simple nitrogen laser at the fair.

- The UniLab-Adlershof of Berlin’s Humboldt University enables visitors to measure the speed of light as it travels through water, air and Plexiglas.

The universities’ student laboratories also supply visitors with information about opportunities for studying physics. The GenaU network provides advice about the research facilities and universities in Berlin and Brandenburg where students can perform experiments and where teachers can attend the appropriate training sessions.

Three interferometers in one device

With its new three-beam interferometer SIOS Messtechnik, based in Ilmenau in the German state of Thuringia, has succeeded in incorporating three interferometers in one device for the first time. This combination enables longitudinal measurements to be made simultaneously in three axes. All three units are served by the same laser. With these interferometers readings can be made of longitudinal measurements and angles, as well as of oscillations in the sub-nanometer range, and they are also used for validation and calibration purposes, at research facilities and in precision and nano-technology.

Measurement technology in optical manufacturing
A technical seminar was held by the PhotonicNet GmbH Optical Technologies Competence Network at the Customer and Applications Centre of Mahr GmbH in Göttingen on 21 February 2008 at which some 100 participants from leading high-tech companies and institutions in Germany, Austria and Switzerland discussed current developments in the use of measurement technology for optical manufacturing. Summing up its results, it was stated that the future belongs to the new measurement systems that are used to support manufacturing processes.

The six technical papers that were presented by the nine speakers covered a range of topics from precision optics made from plastics to new optical measurement methods utilising white light sensors. The speakers emphasised in particular the rapid pace at which developments have taken place in manufacturing technologies for optical components and systems for shaping light.

Three main tendencies are apparent. Firstly: there is an increase in ultraprecise optical surfaces and coatings involving accuracies measured in nanometers, as well as in non-traditional surfaces, for example, aspherical forms. Secondly: refractive and diffractive micro-optics are being used in photonic microsystems, e.g. as compact, integrated lasers in industrial installations. Thirdly: standard components are being produced in ever increasing quantities. All three of these development trends demonstrate the extensive demand that exists for measurement systems to support the manufacturing process, in some cases imposing exacting requirements in terms of precision, robustness and the speed with which the measurements are obtained.

Optical functional layers for meeting the highest quality requirements
Cutting Edge Coatings is the latest firm to be set up at Hannover
In recent years Laser Zentrum Hannover has been instrumental in the development of a number of highly innovative spin-offs. The latest company to be set up is Cutting Edge Coatings GmbH, which is responsible for marketing innovations in ion beam sputtering (IBS) processes. IBS is used in the creation of thin optical functional coatings to meet the most exacting quality requirements. Established in September 2007, the activities of CEC GmbH are intended to support companies in the implementation of an improved IBS process through the provision of coating installations.

The IBS process meets the constantly increasing demands imposed on the optical and structural quality of coating systems, in particular for applications in laser technology. In contrast to traditional thermic vaporisation processes, in which the coating material tends to form porous microstructures through the application of energy levels measured in tenths of an electron volt, the high energy levels used in the IBS process create compact, glasslike structures which are extremely stable and of a high quality. The entire process is one that is clearly defined and easy to follow. Ion generation, atomisation and the formation of coatings take place separately in the process chamber, the process itself is highly stable and reproducible, and contamination by impurities or particulates is kept to a minimum.

Laser integration in production engineering (Initiative LiFt )
The widespread and sustainable expansion of Saxony’s potential for mechanical engineering and plant construction through the use of laser technology, and maintaining a competitive edge – these are the aims of the Initiative LiFt, which was the winner of the competition held by the Federal Ministry of Transport in 2007 that was entitled "Business Meets Science".

LiFt stands for Laser Integration in Production Engineering and is a joint project by the Hochschule (College) Mittweida (FH), the Institut für innovative Technologien, Technologietransfer, Ausbildung und berufsbegleitende Weiterbildung (ITW) e. V. Chemnitz (Training and Innovative Technologies Centre) and the Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS (Institute for Materials and Beam Systems) in Dresden. The network structure is intended to reveal potentials, offer a range of services and highlight the benefits of shorter, more reliable and more economical process chains. In their capacity as developers of technology and as agencies for the transfer of knowledge, the partners in the Initiative LiFt can provide assistance with specific applications for small and medium-sized companies, especially in Saxony, including the manufacturers of laser equipment, mechanical engineering firms and plant constructors, as well as component manufacturers.

In principle, lasers are suitable for inclusion in traditional production methods in almost every group of processes, thereby reducing the length of the processing chain. Such integrative concepts have already shown their effectiveness in industrial applications in various different areas, such as laser beam hardening. New applications can be exploited using modern lasers and improved optics or beam deflection systems, and existing automated solutions can be made more efficient. Cycle times can often be substantially reduced by incorporating a laser in machinery or in a chain of manufacturing processes. The latest developments embrace all kinds of processes and materials.

In a joint project involving the laser production company IPG Laser GmbH, a manufacturer of robots Reis GmbH & Co. KG, ULT AG (aviation engineering), and the engineering consultant Göbel (laser safety), scientists at the IWS and the staff of ALOtec GmbH have developed an installation for demonstrating various laser material processing methods.

Berlin: City of light with a scientific tradition
According to the Scientific State Secretary Hans-Gerd Husung, in the field of optical and nanotechnology Germany can claim “a density of research facilities and repositories of expertise that are almost unparalleled in Germany or in Europe”. Speaking at an event entitled "Nanophotonics – An Economic Factor for Berlin” on 7 February 2008 at the Technical University (TU) Berlin, Husung drew attention to the existence of some 30 research facilities and 270 companies engaged in optical technologies in and around the German capital, with annual sales totalling around 2 bi. euros.

As the politician emphasised: the TU Berlin in particular has a “long and eminent tradition in the field of the optical sciences and technologies”. In the 1930s, at the forerunner of today’s TU, the Technische Hochschule Charlottenburg, Ernst Ruska developed the electron microscope which earned him the Nobel Prize in 1986. The TU Berlin was also the place where “most of the initial work leading to the discovery of the principle of the laser was carried out, and where a whole series of new types of lasers have been developed into fully functioning systems”, Husung pointed out, quoting as an example the development of diode lasers and their application in fibre optic communication networks. And equally importantly, the fact that current research is focussing on photonics is proof of the “wholehearted commitment by this university to continuing this tradition and to exploring previously unknown territory.”

Husung referred to Professor Dieter Bimberg’s work on nanophotonics, and the main focus of this research, into semiconductor quantum points, “as raising expectations of a new generation of optoelectronic and photonic components for use in communications technology, consumer electronics and measurement technology”. The scientific breakthroughs achieved by Bimberg in the mid-1990s, together with the results of research by two other working groups in France in the USA, laid the foundations for present-day nanophotonics. Predications about significant improvements in the properties of semiconductor lasers and the rapid advances in nanophotonics have been largely influenced by the work of the team in Berlin under Prof. Bimberg.

Efforts to overcome the shortage of specialists
The companies involved in optical technologies will only be able to make full use of their potential for expansion if they can succeed in meeting their extensive demand for scientists, engineers and skilled workers. In optical technology there is a particular need for specialised courses of study, for example in laser optotechnology and a masters’ course in optics and photonics.

In this respect Dr. Andreas Nitze, Chief Executive of BERLINER GLAS and Deputy Chairman of SPECTARIS, stated: “Various challenges must be overcome in order to counter the shortage in specialists in optical technologies. In particular this means encouraging people to develop an enthusiasm for technology, making improvements in training and advanced training in Germany, and compensating for the consequences of demographic shifts, by ensuring the closer involvement of older specialists and also by relaxing the conditions regarding immigration and by introducing measures to promote integration. And finally, by providing the right set of conditions, support for efforts to attract more women specialists to this sector should be available.”
