    Polarizing stress tester is an instrument for examining the effect of internal stress or crystal birefringence of glass by using polarized light interference principle. Due to the polarizing stress analyzer equipped with sensitive customers. And the application of 1 / 4 wave plate compensation method, so

the instrument can not only according to the polarization field in the order of interference color, internal stress of qualitative or semi quantitative measurement of the glass, you can also accurate quantitative measurements of glass stress value.
