Polariscope Strain Viewer for Glass and Plastics

Benefits of Polariscope Strain Viewer

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. These effects can be harmful as it may contribute to the product’s failure in service or it can be beneficial, as for example in the inducement of compressive stresses in the surface layers of toughened glass to increase its strength in service.

One of the most powerful methods, where the product is made of transparent glass or plastics, is based upon the photoelastic technique which involves the passing of polarized light through the product and interpreting, qualitatively or quantitatively, the resulting optical interference pattern. In the case of glass products, it is usually the residual stresses which are measured whilst in the case of plastics molding, casting or extrusions it is the strains which generally are of importance. The testing instrument is manufactured by considering relevant parameters and various standards that are introduced by standardized and reputed authorities.

The Presto Polariscope strain viewer for glass and plastics is made to easily detect the defects present in preforms and glass products. This is one of the most accurate quality lab testing instruments that make the use of a monochromatic light source for visual inspection of the testing specimen.  Users can easily rely on this lab testing equipment to test the deforms present in plastic and glass products.

The sample will accurately be placed in the testing area and can be tested to evaluate different types of defects in the specimen. Users will get a sharper and clearer optical viewing experience with the use of this quality lab testing equipment. Presto offers the best Polariscope strain viewer price to our clients. With the help of this quality lab testing equipment, one can detect stress, strains, or even cracks present in plastic and glass products. The wide viewing area present in this testing equipment will give a sharper and clearer optical experience to the users. The samples can easily be tested at 45 and 90 degrees of angles. Presto is a leading Polariscope strain viewer manufacturer and offers this testing equipment embedded with high-quality and advanced testing features.
