The fabrication of high aspect ratio mirrors up to 8-m in diameter presents numerous new challenges in the field of optical manufacturing technology. These mirrors, with aspect ratios in the region of 40:1, represent a new class of optics which requires unique handing, figuring, polishing and metrology approaches. A facility conceived explicitly for the manufacture of high-quality large-aperture primary mirrors for astronomical telescopes is described.
