Applications
High-precision measurement of larger-aperture optical components; flat measurements of conventional optical materials; semiconductor-wafer measurement; ultra-low-stress samples. UV: semiconductors and light-source raw-material suppliers. VIS: lenses, optical raw materials and films; automotive windshields and vehicle glazing; transparent resins; PET and PMMA; glass substrates, quartz glass and sapphire; stress inspection before and after coating; food/pharmaceutical and high-end glass fixtures and minerals; light-guide plates and display components. NIR: infrared-equipment processing or assembly and raw-material manufacturers.
Key Features
Operating principle: stress birefringence changes the polarization state of light passing through a transparent birefringent material. The polarization states before and after transmission are compared. By calculating the combination and compensation of optical vectors, the optical path difference introduced by the sample is measured to determine its stress birefringence. High accuracy: repeatability error <0.5nm. High efficiency: results are available in <1 second, with simultaneous stress information in each dimension. Flexible adjustment: the light source and inspection functions can be customized to customer requirements. Customer service: prompt periodic maintenance, inspection and software upgrades are available.
