Paper Abstract

Today's large aperture telescopes have created a demand for diffraction gratings that are larger than the capabilities of the largest ruling engines. To overcome this obstacle, a method to produce a stable and passive assembly of two or more gratings is required. Replicated monolithic mosaics are produced by the simultaneous optical replication of two submaster diffraction gratings that are aligned relative to one another using a massive kinematic support structure. Relative surface alignment of the individual grating segments of better than 1 arc second is reported.
