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.

Abstract: A scattered light polarimetry (LSP) sub-system of a hybrid system for characterizing stress in a chemically-strengthened (CS) substrate having a top-surface and a near-surface waveguide, includes a LSP light source system, an LSP light source actuator coupled to the LSP light source system, and an optical compensator within an optical path of a LSP laser beam emitted by the LSP light source system. The optical compensator includes a half-wave plate, a half-wave plate actuator, a diffuser, and a diffuser actuator. The LSP sub-system further includes a LSP detector system in optical communication with the optical compensator through an LSP coupling prism having a LSP coupling surface, a focusing lens and a focusing lens actuator, and a support plenum having a surface and a measurement aperture, the support plenum configured to support the CS substrate at a measurement plane at the measurement aperture, and to operably support the LSP coupling prism.
