Application area
This Polariscopeis designed to observe and analyze the distribution of internal strain in transparent plastic preforms.
It has been widely used in the quality control of various plastic rough processing products and finished bottles.
Features
- Defects invisible to the naked eyes such as crystallization or other common defects become visible ;
- 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;
- 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 .
