Application area
This Polariscope is 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
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;

Minimum Order: 1 pieces
