Polariscope Strain Viewer

The Polariscope is designed to analyze internal material stresses and flow characteristics in PET preforms and containers, making it suitable for both laboratory applications and at-line inspection. It enables easy detection of defects by displaying characteristic color patterns—isochromatic fringes when the preform is held parallel to the viewing field, indicating stress magnitude; and isoclinic patterns at a 45° angle, indicating stress direction. Widely used in preform assembly, the ‘Visitec Global’ Polariscope helps identify defects at an early stage, supporting cost reduction and improved production efficiency, and is complemented by a defect chart for better analysis. The device features dual viewing slots for 90° and 45° light orientations, is available in various sizes and weights depending on the model, and operates on a standard 220/240V power supply.
