Automotive Glass – Strainoptics Polarimeters & Polariscopes for Windshields, Sunroofs, and Sidelites
Strainoptics manufactures a complete line of manually operated and automated equipment for measuring surface stress and edge stress in annealed, heat-strengthened, and tempered automotive glass. Please click on the product photo to learn more about that specific instrument.
The GASP® polarimeter is the instrument recommended by ASTM and other international standards groups for measuring surface stress in heat-treated, tempered, or annealed glass. Conforms to European EN-12150 mandates!
For precise quantitative measurement of residual stresses in automotive glass.
PES-100 Automated Edge-Stress
Automatically measures, graphs, and stores edge stress data objectively and accurately.
VRP-100 Reflection Polarimeter
Measure tensile or compressive stresses in the “black band” region of windshields or sunroofs.
Portable Strain Viewer (polariscope) for qualitative stress pattern observation on a small scale.
Polarimeter for quantitatively measuring edge stress in automotive glass (to verify temper quality). Measures both tension & compression.
