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

  1. greatly improvethe measurement accuracywith the combination of Senarmont, Sensitive Color methodand machine vision processing;
  2. equipped with a zoom lensfor 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 ;
