Polariscope Strain Viewer

What is a Polariscope Strain Viewer?

A Polariscope Strain Viewer is an optical inspection system that harnesses the principle of photoelasticity, where polarized light reveals stress-induced variations in the refractive index of materials. These changes highlight stress concentrations, cracks, and defects invisible to the human eye, making it an indispensable device for quality assurance teams in industries dealing with PET packaging, pharmaceutical bottles, cosmetic containers, and glass manufacturing.
