  • Testing principle and application field of glass surface stress meter

    2021-04-28

    The measuring principle of the glass surface stress meter is to use the optical waveguide effect of the ion exchange layer on the glass surface to measure. Divergent light emitted from the light source passes through the slit, converges by the high refractive index cylindrical prism and becomes parallel light. By adjusting the position of the light source
