Product Overview
YLY-03S Polariscope (Glass Stress Tester) is suitable for measuring internal stress values in various glass products, including glassware, glass measuring instruments, glass containers, and glass bottles for pharmaceutical and food packaging.
Testing Principle
YLY-03S Polariscope is an instrument that uses the principle of polarized light interference to inspect internal stress in glass or the birefringence effect in crystals. Equipped with a sensitive tint plate and utilizing the quarter-wave plate compensation method, this instrument can not only qualitatively or semi-quantitatively measure the internal stress in glass based on the interference color sequence in the polarization field, but also accurately measure the numerical value of the internal stress.
