Product Description:

This Polarimeter adopts automatic Senarmont to measure the internal stress in transparent objects . In

the previous manual Senarmont method, the observer needs to determine the brightest point and the darkest point by their eyes, thus operation errors can not be prevented .

This device automatically detects the image luminance, thereby finding the darkest point precisely . By inputting sample photoelastic constant and thickness in advance, the stress value will be calculated by the computer . In addition, Sensitive Color method is used to clearly define the direction of stress.


1.greatly improve the measurement accuracy with the combination of Senarmont, Sensitive Color method and machine vision processing;

2.equipped with a zoom lens for detection of small samples ;

3.measurement can be finished in 10s;

4.save data and images automatically with a laptop


1.measurement of residual stress in various types of glass products ;

2.stress presence and stress distribution in plastic products ;

3.phase difference measurement of optical film ;

4.stress presence in crystalline materials

Detection objects

1.lighting industry, such as light bulbs, light tubes

2.beverage and medical packaging industry, such as drink bottles, Penicillin bottles, ampoule bottles ;

3.household glassware, such as red wine glass, crisper, salad bowl ;
