[[BR]] [[BR]]By connecting studies across a variety of physical scales, from individual star forming regions to galaxy-wide coverage, LVM will help us to understand the physics governing star formation, the structure and energetics of the interstellar medium (ISM), and ultimately, the evolution of galaxies. The survey, undertaken at Las Campanas Observatory in Chile, will start in late 2021 and will cover the bulk of the Milky Way disk, the Magellanic Clouds, and a sample of Local Volume galaxies. [[BR]][[BR]]Surveying such a wide area of sky requires a unique type of optical system, and MPIA has taken the lead role in producing the telescopes for LVM.  Each of the four telescopes has a diameter of only 16 cm, making them considerably smaller and lighter than the instruments they feed. The architecture of the LVM survey presents unique challenges to telescope design. This, coupled with the need for reliable measurements over years, leads to some unconventional design choices.[[BR]][[BR]]Presentation: English[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2020S1/2020-01-31_LVMFocalPlanes.pdf Slides: English] [[BR]]Questions: German, English ||

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.
