Paper Abstract

Interferometric measurements are often used to assess the homogeneity of optical glass. In order to determine the uniformity of refractive index of optical glass due to chemical fluctuations within the glass, residual stress from thermal processing must be low. We provide data showing the effects of residual stress, resulting from the annealing process, on the transmitted wavefront used to grade optical glass quality.
