The Preform Strain Viewer Polariscope is a solution for detecting defects in plastic bottles. Our expertise in optical instruments ensures the highest quality and precision in this state-of-the-art product.

Manufactured in China, the Preform Strain Viewer Polariscope is designed specifically to observe and analyze the distribution of internal strain in transparent plastic preforms. It has become an essential tool for quality control in various plastic rough processing products and finished bottles.

Equipped with advanced features, our Polariscope brings defects that are invisible to the naked eye into clear visibility. It enables users to identify common defects such as crystallization with ease.

By placing the plastic preform on the Polarizer at a 45° angle, users can observe the colored birefringent stripes at the edge of the preform. Alternatively, when placed at a 0° or 90° angle, black birefringence stripes in the central part of the preform are displayed.

To ensure comprehensive analysis, the Strain Viewer utilizes not only white light but also Sodium light, making it suitable for testing colored preforms or finished bottles. Additionally, it provides 12 different defect analysis functions, accompanied by colored defect comparison pictures, which serve as valuable references for improving the preform production process.

The Preform Strain Viewer Polariscope comes with specifications that enhance its performance and usability. The viewing field measures 200200 mm, offering a broad perspective for accurate analysis. Its overall size of 300335330 mm ensures a compact and ergonomic design.

Powered by a main voltage of 220 V AC, it incorporates LED light sources, including both White and Sodium light options. With a gross weight of 10KG, the Polariscope is conveniently packed in one carton measuring 4545*32cm.

Suzhou Ptc Optical Instrument is dedicated to providing specialized Polariscope solutions for plastic preforms. With our product, you can confidently enhance your quality control processes, ensuring the production of flawless plastic bottles.
