Polarized Light Strain Viewer

The Polarized Light Strain Viewer uses polarized light to detect flaws in molded plastic, PET and Preforms, Glass, Transparent Materials, Acrylics and other materials that cannot be viewed with the naked eye. The instrument is helpful for different industries to catch errors in the molding or heating process, in preforms. This prevents expensive repairs and saves time and money.

Presto supplies and manufactures the highly efficient polarized light strain viewer for testing the quality and transparency of the products. The instrument helps the manufacturers for assuring the best quality products to the customers. The working is based on the principle that any change in refractive index is because of different strain distribution. This leads to the lower transparency of the material. The instrument is provided with variety of sizes and specifications as per the requirements of the clients

Photoelasticity occurs in PET, Preforms and Glass products that indicate the change in the refractive index of the material. The change in the refractive index occurs when non-uniform strain distribution is observed throughout the material. The instrument is beneficial to solve the issue of photoelasticity, which is the significant problem for the manufacturers of PET and preform. The instruments assured the prolonged service life and precise testing procedures.
