数显应力仪
Semi-auto Computerized Polarimeter (Ref : PSV-702)
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 .
Features
- greatly improvethe measurement accuracywith the combination of Senarmont, Sensitive Color methodand machine vision processing;
- equipped with a zoom lensfor detection of small samples ;
- measurement can be finished in 10s;
- save data and images automatically with a laptop
Application
- measurement of residual stress in various types of glass products ;
- stress presence and stress distribution in plastic products ;
- phase difference measurement of optical film ;
- stress presence in crystalline materials
Detection objects
- lighting industry , such as light bulbs, light tubes
