Abstract: A method of producing glass-based articles having sections of different thicknesses is provided, where a maximum central tension in a thinner section is less than that of a thicker section. The method includes reducing the thickness of a region of a glass-based article that includes a compressive stress layer extending from a surface to a depth of compression to form a glass-based article with multiple thickness regions, and then ion exchanging the glass-based article to form a stress profile in the thinner region that has a maximum central tension that is less than a maximum central tension of a stress profile of the thicker region. The glass articles produced by the method are also provided.

Abstract: The prism-coupling systems and methods include using a prism-coupling system to collect initial TM and TE mode spectra of a chemically strengthened article having a refractive index profile with a near-surface spike region and a deep region. The initial TM and TE mode spectra are examined to see if they fall within a preferred measurement window that can produce an accurate estimate of the knee stress to within a select tolerance. If not, then measurement configuration of the prism-coupling system is changed and new TM and TE mode spectra are collected. This process is repeated until the new TM and TE mode spectra fall within the preferred measurement window. The new TM and TE mode spectra are then used to determine the knee stress. Changing the measurement configuration can include changing at least one of the measurement wavelength, interfacing fluid thickness and interfacing fluid refractive index.
