Fully Automatic Polarimeter 145

Fully Automatic Polarimeter 145 is a stress measurement device that automatically detects the retardation and the slow axis direction of transparent objects, which displays birefringence phenomenon under polarized light. A high resolution camera is adopted to take sample pictures from different angles. By analyzing change in polarization state caused by stress presence with specific algorithm, the optical retardation value will be measured. By applying the retardation to a formula, stress value in the sample will be calculated automatically.

Features of Fully Automatic Polarimeter 145


  • Full-automation: One-key automatic stress measurement within the whole viewing field.

  • High efficiency: A single measurement can be finished in 15s under high-speed mode.

  • Strong result analysis function:

    ① 3D stress image within the viewing field

    ② 2D Area stress analysis

    ③ 1D line stress analysis

    ④ Point stress analysis

  • High accuracy: Made with high-quality materials and advanced technology to ensure high repeated measurement accuracy.

  • No background interference: Eliminating environment interference by calibration under background light before the first measurement.
