Polarization stress meter for medicine bottle / Convenient operation
Polarization stress meter for medicine bottle YLY-03 The polarized light interference method can accurately detect the stress value of glass wine bottles. This instrument meets the requirements of the new version of drug packaging materials, and is suitable for polarized light measurement of stress values in glass wine bottles of various capacities. It is widely used in pharmaceutical enterprises, glass products factories, and quality inspection institutions.
Next, we will briefly introduce Polarization stress meter for medicine bottle The principle of use, including qualitative measurement principle and quantitative measurement principle.
（1） Qualitative measurement principle:
（2） Polarization stress meter for medicine bottle The internal stress value of glass wine bottles can be measured qualitatively or semi quantitatively by observing the interference color sequence in the polarization field using the polarized light interference method.
（3） Principle of quantitative measurement:
（4） The sodium light emitted by the light source passes through the polarizer to become linearly polarized light, and then the linearly polarized light passes through the tested sample with birefringence optical path difference and 1/4 After the wave plate, its vibration direction will rotate a certain angle. angle Q The value of and the birefringence optical path difference of the tested sample δ Is proportional, and the relationship is: λ Take sodium light as five hundred and eighty-nine point three ， δ by 589.3Q/180=3.27Q 。 When Q=1° When, δ=3.27 Nanometer (equivalent to three point two seven Nanometer).
Through the above principle, we can accurately measure the stress value in the glass wine bottle, so that the subsequent reheating and burning can disperse the concentrated stress. This instrument not only meets the requirements of new drug packaging materials, but also can be widely used in various fields, providing strong technical support for quality inspection institutions, glassworks and pharmaceutical enterprises.
