Polariscope Computerized

Presto’s Polariscope is strategically designed to identify the defects and strains in PET structures and glass structures. It is widely used in the testing of PET preforms and glass structures. It works on the optical principle where refraction of light ray is considered. In perfect structures, polarized light follows a straight path and does not deviate when passes through the medium. When the light encounters any strain or defect like bubble, it deviates from its path and creates birefringence effects. For every defect, an identifiable pattern gets created which is matched with the reference chart. This is a natural phenomenon and thus it becomes easy for the manufacturer to identify the defect based on the birefringence pattern.

The instrument comes with a polaroid lens and incident light. The specimen is strategically placed between the lens and light to make the observations.
