PTC Computerized Glass Polariscope – Stress Analysis Magnifier for Optics

Computerized  Polariscope (Ref : PSV-702  )

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. 

Features

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

Application

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 ;

4.  other glass products , such as contact lenses, solar glass ,automobile glass;

5.  optical crystals, such as calcium fluoride
