This design,   while previously state-of-the art, leads to systematic errors which is   beginning to limit our ability to study some of the most challenging,   and consequently most interesting planetary systems. In the era of   adaptive optics at large telescope facilities worldwide, it is now   possible to inject a diffraction-limited input into single-mode optical   fibres to feed next generation RV spectrographs. These have a reduced   instrument volume, a stable input source, and can offer improved overall   stability and precision for RV over their multi-mode fed counterparts.[[BR]][[BR]]iLocater   is a next-generation precision RV spectrograph under development for   the Large Binocular Telescope (LBT). It is one of the first astronomical   spectrographs to use single-mode fibres for precision radial velocity   measurement and will provide high resolution (R~150,000-240,000) NIR   spectra in a stable environment. Jonathan Crass will present an overview  of the  instrument, its current status and novel science programs.[[BR]][[BR]]Presentation: English[[BR]][ Slides: English] [[BR]]Questions: German, English ||

For passive structures, these designs  present in most cases a minimum in terms of required mass under given  safety limitations and user comfort constraints.[[BR]][[BR]]However, it is  possible to stay within these limits and reduce the total embodied mass  even further by introducing active structures, which we refer to as ''ultralightweight design''.  Through their various actuators, these structures can adapt to external  loads and disturbances, thus increasing the utilization of the  structure and its elements, which leads to even lighter designs.[[BR]][[BR]]In  light of the expected construction activities within the next 20-30  years, this can help saving millions of tons of concrete and steel and  significantly reduce waste production and CO,,2,,-emissions of  the construction industry. What’s more, the developed methods and ideas  can also be applied to any large-scale applications where high masses  are critical, such as space flights and airplanes, harbor cranes, ships  and even telescopes and their instruments.[[BR]][[BR]] The talk will focus  on ideas, methods and results of our research in the context of adaptive  ultralightweight structures with a focus on large civil engineering  structures. At the end, possible implications of this technology for  telescopes and their instruments will be presented.[[BR]][[BR]]Presentation: German[[BR]][ Slides: English] [[BR]]Questions: German, English ||

     12|| '''22.11.2019[[BR]](11Uhr, MPIA Hoersaal)''' || ''' Prof. Dr. Andreas Heinrich (Aalen University)''' || '''Additive Manufacturing of Active and Passive Optical Components[[BR]]'''[[BR]]The  development of additive manufacturing methods has made enormous  progress within the last years.  Most of the work has been focused in  the implementation of mechanical parts, but additive manufacturing  technologies also offer great potential in the optics area, allowing new  designs with more degrees of freedom and with it completely new  approaches.[[BR]][[BR]]This talk will present and compare the most important  methods for additive manufacturing of synthetic materials.  Besides,  the most characteristic properties of the additive manufactured optics  will be presented.  Of special importance is the volume scattering and  the surface quality.  To be able to improve them, corresponding  subsequent machining is necessary, which will also be discussed.[[BR]][[BR]]A  very important part of the talk deals with the discussion of various  examples of additive manufactured optical parts.  On one hand additive  manufactured passive optical elements, like optical beam splitters,  micro lens arrays, or optics with complex forms will be presented.  On  the other hand active optical elements, like 3D printed liquid lenses,  printed organic light diodes or additive manufactured Random Laser will  be discussed.[[BR]][[BR]]The talk ends with a presentation of the current  design of a robot based on an additive manufactured platform being  develop currently at the Center for Optical Technologies of the Aalen  University.[[BR]][[BR]]Presentation: German[[BR]] [ Slides: English] [[BR]]Questions: German, English ||

'''[[BR]]''' ''' || '''Thomas Ruppel (!SwissOptic AG)''' || '''Modern fabrication of high-precision-optics - [[BR]]a journey along the optical manufacturing chain'''[[BR]][[BR]]In  many cases our society's development is driven by the progress in  photonic technologies. Take for instance:  Steadily shrinking  semiconductor structures allow for digital systems of higher  performance, modern optical surgery is key for a broad treatment of a  population, which is getting older and older, and air or space borne  high-performance optical components are vital for environmental  surveillance with optical communication at a daily growing data rate.  Prerequisites behind all these applications are typically very precise  optical components like beam splitters, mirrors, lenses or polarization  optics, which have to be produced in high quantity and very high  quality.[[BR]] [[BR]]In the context of this talk the requirements for those  components and the manufacturing steps will be presented. In some  outstanding cases even exotic ideas and technologies are necessary,  which will be explained by practical examples.[[BR]][[BR]]Presentation: German[[BR]][ Slides: English] [[BR]]Questions: German, English ||

This talk  is a distillate of those meetings about sustainability with respect to  our institute.[[BR]][[BR]]Presentation: German[[BR]] [ Slides: English] [[BR]]Questions: German, English ||

In parallel, he will introduce the programm for the "Origins of  Life Labs" here at MPIA.[[BR]][[BR]]Presentation: German[[BR]] [ Slides: German] [[BR]]Questions: German, English ||
