Preform Strain Viewer or Advanced Preform Strain Viewer Polariscope for Detecting Defects in Plastic Bottles offers a comprehensive solution for identifying quality issues in plastic preforms. Designed for ease of use, this innovative instrument enables users to visualize internal strains in transparent plastic materials. The user-friendly interface allows quick placement of preforms on the polarizer at specific angles to observe birefringent patterns that indicate defects.

Equipped with advanced features, this Polariscope is essential for quality control in the plastic manufacturing industry. It can reveal defects such as crystallization that are invisible to the naked eye. By analyzing the distribution of internal strain, manufacturers can enhance their production processes and ensure the creation of finished products. The viewing field measures 200 x 200 mm, providing ample space for thorough analysis.

Features
1. Defects invisible to the naked eyes such as crystallization or other common defects become visible ;
2. When the plastic preform is placed on the Polarizer at a 45° angle, the colored birefringent stripes at the edge of the preform can be observed;
3. When the plastic preform is placed on the polarizer at a 0°or 90° angle, black birefringence stripes in the central part of the preform will be displayed;
4. In addition to white light, Sodium light is also used to test colored preforms or finished bottles;
5. Besides , this Strain Viewer provides 12 kinds of defect analysis functions.

12 kinds of colored defect comparison pictures will be attached to instruct related improvements in preform production process.
