Abstract:
Apparatus, systems and methods for improving strength of thin cover glass for electronic devices are disclosed. Optical coherence tomography analysis may reveal fine details of a residual stress profile within chemically strengthened cover glass. One or more parameters of chemical strengthening treatments may be adjusted, based upon the analysis of the residual stress profile.
