Polariscope Strain Viewer

Pacorr’s Polariscope Strain Viewer is a high-precision optical inspection tool designed to evaluate stress distribution and transparency in PET preforms, glass products, and other transparent materials. It plays a critical role in quality control by detecting internal strain patterns that may compromise product integrity.The instrument works on the principle that variations in the material's refractive index, caused by uneven strain, reduce transparency a phenomenon known as photoelasticity. This is particularly significant for manufacturers of PET and glass items, where undetected internal stress can lead to breakage or performance failure.Pacorr offers two advanced models: the Polariscope Digital Model and the Polariscope Computerized, each tailored to different inspection needs. The Digital model features a digital display for clearer visualization and user-friendly operation, making it ideal for modern QC labs. Built with corrosion-resistant materials and a refined zinc and chrome finish, these instruments are designed for long-term, reliable use. The grey and blue exterior adds a sleek, professional look to the unit.Every Polariscope unit is supplied with a calibration certificate traceable to NABL-accredited labs, along with a comprehensive instruction manual. Available in multiple sizes and specifications, Pacorr’s Polariscope is the go-to solution for manufacturers seeking accuracy, durability, and dependable quality assurance.Dual light source – monochromatic and polarizedCompact and table-top designComes with standard strain interpretation chartHigh transmission LED illuminationSuitable for PET preforms and blow-molded bottlesOptional digital model with camera and software analysisPET bottle manufacturingPreform quality testingCosmetic packaging inspectionPharmaceutical bottle QCTransparent molded parts analysisLaboratory R&D for polymers and plastics
