Measurement of Residual Stresses in Molded Glass Lenses

Article Preview

Abstract:

Residual stresses inside molded glass lenses contribute to image quality degradation. In this research, a circular polariscope was employed to investigate the residual stresses inside molded glass lenses. Residual stresses were calculated from optical measurements obtained by using of the circular polariscope. From the measurements both the magnitude and distribution of residual stresses in a molded glass lens were obtained.
