Presto's Glass & Plastic Polariscope - Strain Viewer is the best and highly effective testing device which is used to measure the residual stresses and strains that are introduced during the manufacturing process of the products that severely affects the strength of the product.
Polariscope Strain Viewer - Deluxe

Polariscope Strain Viewer - Deluxe

Presto provides the Polariscope, an exceptionally effective strain viewer designed to assist manufacturers in testing the quality and transparency of their products, thereby ensuring the highest standards of quality assurance for customers. The Polariscope operates on the principle that variations in refractive index indicate differing strain distributions, resulting in reduced material transparency.

Polariscope

 

The polariscope is an extremely futuristic lab testing instrument that is necessary to be installed in the manufacturing industries that deal with PET & glass products. 

The instrument is designed to determine the uncertainties and irrationalities in the preform stage of a product to avoid hefty losses due to faulty mass production. 

The Polariscope allows the manufacturer of the preform to visually analyze the uncertainties by comparing them through the ideal chart. The instrument simply assesses the specimen under a dual lighting mechanism that exposes its irrationalities. The two light assemblies installed in the polariscope are sodium lamp & CFL bulb for superficial testing.
