Paper Abstract

Hextek Corporation is an optics design and manufacturing firm located in Tucson, Arizona. Our primary efforts have been in the refinement of our Gas Fusion process that renders lightweight mirror blanks in a fraction of the time required by conventional methods. Our borosilicate lightweight mirrors have found applications in large laser systems, astronomical telescopes, and system test benches. This paper describes the design and construction of an 84 cm Gas Fusion, center-plane-mounted, secondary mirror blank. This blank was purchased by the Astrophysical Research Consortium for incorporation into the 3.5 meter telescope located at Apache Point, New Mexico. Work on the secondary began in May 1988 and was completed the following month and then delivered to an optics shop for generating and polishing.
