Abstract

In March 1985 a 1. 8m diameter, f/1 focal ratio, lightweighted honeycomb sandwich mirror blank was cast at the Steward Observatory Mirror Laboratory. The front surface curvature was formed by spinning molten borosilicate glass at 15. 6 rpm. The purpose of the casting was to test the method to be used to make 8m honeycomb mirrors. The blank will be used to test a polishing method for f/1 paraboloids.
