Overview
Residual stress in materials and transmitting components on optical production lines affects physical properties, product quality and application performance. Stress-birefringence testing is therefore an important part of quality control. The stitching stress meter automatically measures and evaluates stress birefringence. Fully automatic stitching enables fast, accurate measurement of large samples such as fused silica and calcium fluoride. Systems with apertures up to 1000mm × 1000mm can be customized.

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. Available units: polarization angle (°), optical retardation (nm), and normalized retardation (nm/cm, nm/mm).
