Semi Automatic Polarimeter Stress Magnifier Polariscope Stress Meter for Glass and quartz products

Product Details

Semi-automatic Polarimeter (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 ;
