摘要： 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 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 to improve measurement accuracy are also disclosed.

摘要： The present invention is directed to an apparatus for grinding or polishing at least one edge of a glass substrate. The apparatus includes a grinding unit configured to remove a predetermined amount of material from the edge when in an aligned position. The grinding unit applies a predetermined force normal to the edge. An air bearing slide system is coupled to the grinding unit. The air bearing slide system is configured to slide along a predetermined axis on a thin film of pressurized air that provides a zero friction load bearing interface. A linear actuation motor is coupled to the air bearing slide system. The linear actuation motor is configured to control the movement of the air bearing slide system such that the grinding unit is moved from a non-aligned position to the aligned position.

摘要： 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.
