Visual photographic, and interferometric tests were performed on the space shuttle overhead windows to characterize the optical quality of these windows. An Air Force tri-bar target was viewed with an 8-in. telescope and a 5-in. telescope for the photographic and visual tests. A Zygo Mark IV interferometer was used for the interferometric tests. Results showed that the windows significantly degraded the performance of both telescopes. At least a 160% degradation in resolution was seen. The results of an independent test conducted by the Armstrong Aerospace Medical Research Laboratory are reviewed and found to corroborate the Aerospace results.
