Presto presents Polariscope Strain viewer, a high-quality testing instrument that is used for checking the quality of PET preforms. It works on the principle that any change in the refractive index of a material indicates strain in that material which affects the quality of the material.

Presto offers two models of Polariscope for preform equipment namely, Polariscope DX and Polariscope Computerized that are made from best quality of raw materials for long service life and high level of precision. Presto offers a variety of sizes and designs Polariscope for glass and preform according to requirements of our clients.

Prestos Polariscope is a strain viewer for glass and PET Preform that is provided with a metallic base and is painted in autumn gray and blue colour. Along with that, it is also provided with zinc/chrome plating which provides the equipment, excellent resistance from corrosion. A user manual and a calibration certificate are provided with the instrument which is traceable to Labs approved by NABL. With these features and specifications, Presto offers a robust and precise solution to check the quality of the PET preforms used in plastic industry and that also at very competitive prices.

Polariscope is an optical device and used for the defect identification in PET preforms. Preforms develop internal defects due to external strain. These defects might create weak points when blown moulded into bottle. To avoid this, the preforms are tested prior mass production. The device has an incident light and polaroid lenses. The incident light passes completely through the test medium without any refraction. As a light encounter a defect, it changes its path doubly and create different patterns of light.

Due to polaroid nature of lenses, the birefringence of light forms. This birefringence creates different patterns depending upon the type of the defect. The pattern can be matched with the defect chart to identify the defect. The sample is tested at two different angles, 45 and 90. The strain viewer can be used for PET preforms and glasses also. It is equipped with two types of incident light Monochromatic and Sodium. The device can be connected with the computer for defect identification and report generation.
