Many astronomical space missions observe at wavelengths which are absorbed by the atmosphere, as for example some infrared, ultraviolet or x-ray bands. Especially UV and x-ray optics have very stringent alignment tolerances due to the small wavelengths. Consequently, telescopes and instruments can only be tested at their operational wavelengths under vacuum conditions. Traditional methods for fixing optical elements and subassemblies (e.g. gluing, soldering, welding, laser based methods) are executed under atmospheric conditions and by using reference interfaces or other wavelengths to ensure their correct alignment. Being able to perform critical alignment steps under vacuum conditions at the design wavelengths would be the most direct and accurate way and reduce risks associatedwith indirect alignment methods or using in-flight mechanisms for alignment corrections.The activity shall develop and test novel technologies for the alignment, assembly and integration of optical assemblies under vacuum.Procurement Policy: C(3) = Activity restricted to SMEs RD Entities.
