Paper Abstract

A kinematic whiffle tree type mount for a 60 inch Pyrex spherical mirror that is figured on both sides was designed and built at the Optical Sciences Center. Interferometric testing of the optic was performed in two orientations and these results were then compared with the results of finite element analyses. This comparison was facilitated by the use of computer program PCFRINGE and PHASE. The results of the comparison indicates that analytic predictions, based on the methodology presented herein, will accurately predict the performance of kinematic mirror mount configurations.
