Abstract

The standard method of determining the index homogeneity of optical-quality glass windows has been extended to improve the accuracy of the results, and to enable disks of over 20 in. (50 cm) in diameter to be evaluated with comparative ease. The evaluation of a 34 in. (85 cm) diameter disk of fused silica illustrates the new method.
