Paper Abstract

The National Optical Astronomy Observatories (NOAO) have been working for several years to develop the technology for 8-m telescopes using structured borosilicate glass primary mirrors. In March 1989 the final stage in this technology development program began with the delivery of a 3.5-m mirror blank, cast under NOAO contract at the University of Arizona Mirror Lab. The project will have four phases: (1) initial fabrication, (2) testing of support and thermal systems, (3) aspherizing the mirror and rework of the support and thermal systems, and (4) final acceptance test. At the conclusion of this effort there will be a finished 3.5-m f/1.75 mirror, which will then become the heart of the new WIN telescope on Kitt Peak.
