Polarization Imaging for measuring Stress in Glass

Uncover the invisible - Polarization Imaging Solutions for Inline Stress Inspection

State-of-the-art polarization cameras, available from a number of different manufacturers, capture polarization images in one single acquisition. Using this data, our software library generates stress images and displays precise magnitude and orientation that help you determine the retardation and position of any potential residual stresses in the glass and immediately identifies any nonconforming products.


Our software modules
        100% inline stress inspection of glass using linear polarization
        Orientation independent analysis of stress in glass
        Measurement of high-stress, e.g. in tempered glass
