Plastic Polariscope（Ref: PSV-801 )

Principle

The residual stress of transparent plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light from he polarized lamp will be divided into different units, which produce optical interference phenomenon(ripple patterns) in turn.

From the observation of colored patterns, you can see stress distribution directly, then evaluate and improve the molding process.

The inspection of plastic molds is complex as the colored patterns cased by stress is irregular. For example, a qualified mold will have a large amount of stress released by tension.
