A, instrument USES
Stress is widely used optical instrument factory, glass, transparent plastic products industries and other optical materials such as stress value of testing unit, but also for measuring scientific research unit measuring optical crystal light path difference value.
Stress instrument to measure is transparent objects from the internal stress due to the double refraction instrument. The double refraction (the source of stress), is due to the uniform cooling or external mechanical function of the causes.
Second, instrument characteristics
Stress instrument is the application of polarized light interference principle glass or crystal double check the internal stress of refraction instrument. Because of all the eyes with a wave, so the instrument can not only according to field of polarization interference color sequence of quantitative qualitative or half measuring the internal stress of glass numerical.
