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: Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a first transition region comprising a first transition width and a first transition surface area extending between a first surface area of the first portion and a first central surface area of the central portion with a first average angle. In aspects, the first average angle is from about 167° to about 179°. In aspects, the first transition width is from about 150 micrometers to about 700 micrometers. Methods comprise disposing an etch mask over the first major surface of the foldable substrate before etching the foldable substrate. In aspects, the etch mask comprises a first polymer layer positioned between a first barrier layer and the first major surface. In aspects, the etch mask comprises a positive photoresist.

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.
