A polariscope is a precision optical device used to examine internal stresses in transparent materials like plastics and glass. It utilizes polarized light to reveal stress patterns that are otherwise invisible to the naked eye. The polariscope is essential in industries such as packaging, PET bottle manufacturing, and automotive parts, where product durability is critical. By detecting stress concentration points, it helps in ensuring quality and safety in molded products. Available in both monochromatic and strain-viewing models, this device is highly efficient for quick and accurate stress inspection, making it a key instrument for research and quality control labs.
