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 prism-coupling system has a light source configured to generate sequential measurement light beams or reflected light beams having different measurement wavelengths. The different measurement wavelengths generate different TM and TE mode spectra. The light source can include multiple light-emitting elements and optical filters or a broadband light source and optical filters. The optical filters can be sequentially inserted into either the input optical path or the output optical path of the prism-coupling system.

Abstract: The hybrid measurement system includes an evanescent prism coupling spectroscopy (EPCS) sub-system and a light-scattering polarimetry (LSP) sub-system. The EPCS sub-system includes an EPCS light source system optically coupled to an EPCS detector system through an EPCS coupling prism. The LSP sub-system includes an LSP light source optically coupled to an optical compensator, which in turn is optically coupled to a LSP detector system via a LSP coupling prism. A support structure supports the EPCS and LSP coupling prisms to define a coupling prism assembly, which supports the two prisms at a measurement location. Stress measurements made using the EPCS and LSP sub-systems are combined to fully characterize the stress properties of a transparent chemically strengthened substrate. Methods of processing the EPCS and LSP measurements and enhanced configurations of the EPCS and LPS sub-systems to improve measurement accuracy are also disclosed.

Abstract: Systems and methods of performing a stress measurement of a chemically strengthened glass using a light-scattering polarimetry system include adjusting the intensity of a light beam from a light source in an illumination system using a rotatable half-wave plate and a first polarizer operably disposed between the light source and a rotating light diffuser that has a rotation time tR. The first polarizer is aligned with a second polarizer in a downstream optical compensator to have matching polarization directions by rotating the rotatable half-wave plate to a position where the exposure time tE falls within an exposure range tR≤tE. The method also includes performing an exposure using the exposure time tE to obtain the stress measurement. One or both of the half-wave plate and first polarizer can be tilted to avoid deleterious back-reflected light from entering the light source.

Abstract: Apparatus includes a sample holder with a cavity and a plurality of devices configured to hold a curvature of a curved substrate in a fixed configuration. Apparatus includes two prisms with a viewing apparatus of the sample holder configured to translate therebetween. Methods can include disposing the curved substrate in the sample holder, transmitting a first beam, translating the sample holder, and transmitting a second beam. Alternatively, apparatus include a light scattering-polarimetry sub-system configured to emit a first beam to impinge an end surface of coupling prism and detect at least a portion of the first beam impinging the first surface of the coupling prism. The apparatus includes an evanescent prism coupling spectroscopy sub-system configured to emit a second beam to impinge a first surface of the coupling system and detect at least a portion of the second beam impinging the second surface of the coupling prism.
