Fully Automatic Polarimeter 280

It is an advanced automatic stress measurement device that measures the retardation which displays birefringence phenomenon under polarized light. The light travels through the polarizer to become circular polarized light. When the stressed sample is placed, the slow and fast axis of birefringence produces the retardation, and the outgoing light becomes elliptical polarized light. Through the phase retarder and polarization camera, the phase and axial angle change of the polarized light under the influence of stress are measured, thus calculating the sample stress value and the slow/fast axis direction.


Features of Fully Automatic Polarimeter NMV-280


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

  • Enlarged retardation measuring range: Adopt specific optical components to enlarge the retardation range up to 280nm;

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

  • Strong result analysis function:

    ① 3D stress image within 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;

  • Adjustable viewing field: The measurement viewing field can be adjusted based on sample size to ensure high-resolution images.
