StrainScope® Stepper

  • Function

    Real-time polarimeter for fast and precise measurement of the stress birefringence in large-format optical materials and components

    Internal stresses affect the mechanical and optical properties of products made of glass and plastics, both in the manufacturing process as well as in the further processing.

    With the StrainScope Stepper you can measure residual stresses with high spatial resolution precisely and reproducibly – in real time and including orientation (azimuth angles). The telecentric optics enable the measurement of thick materials without parallax errors and the measurement of residual stresses in materials with intrinsic birefringence. The motorized positioning stage features automatic stitching of larger samples up to 220 x 220 mm².

    The convenient archive function ensures that all measurement results are fully documented.

  • Features and Benefits

    • Fast and easy operation
    • Integrated XY positioning table with automatic stitching
    • Objective, reproducible and precise measurement results
    • Complete traceability through automatic result documentation

  • Application example

    Automatic measurement of the stress distribution in silicon carbide wafers (4H-SiC4) with a diameter of up to 200 mm
