Space Optics and Interferometry Cleanroom
The space optics and interferometry cleanroom (ISO class 7, with class 3 laminar flow cabinets) is where precision-aligned, robust, ultra-stable optical components and assemblies for LISA Pathfinder were assembled, integrated, verified and tested. The labs are currently used for the development, construction and testing of space-flight technologies for the ESA-led LISA Mission. For LISA Pathfinder, a gravitational wave detector technology demonstration mission, optical benches were constructed here using the hydroxide catalysis bonding technique to manufacture quasi-monolithic optical components, sub-assemblies and benches. This work required optical components to be aligned and bonded with high precision (<4 micrometre and <10 microradian).
Now, for the larger quantities of optical sub-assemblies required for LISA, this high precision bonding is achieved with an automated alignment and component placement system. Through engagement with these activities, the labs are well equipped to engage in commercial, industrial or aerospace of similar optical assemblies.
