Metrology and mechanics for manufacturing space-based x-ray grating spectrometers

Small errors in critical dimensions (CDs) or deformation of optical components can lead to severe performance degradation in high-resolution imaging and spectroscopy tools. Consistent innovations towards more precise optical elements and assembly procedures have led to high-resolution optical systems in many fields - including telescope, microscopy, lithography, and display technologies. A space x-ray telescope needs more stringent requirements as it observes distant space objects using a limited number of x-ray photons in a harsh space environment. The optical instruments for x-ray telescopes need to be high-resolution, efficient in collecting x-ray photons, and lightweight. Optical elements in x-ray telescopes have large-apertures (typically around 1-2 m²) which are realized by populating them with > 1000 high-quality optical sub-elements (i.e., mirrors or gratings).
