Paper Abstract

The 11-meter primary mirror of the Hobby-Eberly Telescope consists of 91 hexagonal segments. Each segment is 1 meter across (flat to flat). The unique design of this telescope allows for a spherical radius of curvature on each segment. Requirements are that each segment's radius of curvature match to within +/- 0.5 mm of the nominal 26,165 mm radius, and that the surface figure be within 0.033 micrometers RMS. The optical fabrication, testing, and assembly of these segments will be discussed along with a description of the segment mounting scheme.
