Abstract
LINC-NIRVANA is an innovative imaging interferometer fed by dedicated multi-conjugated adaptive-optics systems (MCAO). The instrument combines the light of the two,
8.4 meter primary mirrors of the LBT on a single focal plane, providing panoramic imagery with 23 meter spatial resolution.
LINC-NIRVANA is entering its final integration phase, with the large adaptive-optics and interferometric subsystems coming together in the clean room in Heidelberg. Here,
we report on progress, including insights gained on alignment, calibration, and vibration control in large interferometric instruments.
