In the context of quantitative stress measurement, this polarimeter can be used to analyze the birefringence of a material. Birefringence is a property where a material has different refractive indices along different axes, often induced by stress. By measuring the changes in the polarization of light passing through the material, the polarimeter can provide data on the internal stress retardation.
Compatibility among various sample size: The maximum testing area in one measurement can be up to 400*400mm.
Premium Performance: Adopting imported optical components to display clear stress images.
Ease of Use: Convenient and quick wave plate switching using a pull rod in the polarizer.
Real-Time Display: Provides immediate visualization of stress presence and distribution.
Long Service Life: Made with high-quality materials and advanced technology, ensuring a long service life and reducing maintenance and replacement costs.

1. Optical Measurement Principle
The PSV-413L utilizes polarized light transmission to analyze stress distribution in transparent materials. As light passes through the sample, stress-induced birefringence causes measurable changes in the light's polarization state, which are captured by precision optical sensors.
2. Manual Operation Process
Operators place large size samples (up to 410×310mm) on the polarizer and rotate the calibrated analyzer manually. The system visually displays stress patterns through interference colors, allowing real-time observation of both magnitude and direction of stresses.
3. Data Interpretation
Built-in 1/4 wave plates convert birefringence into visible color patterns corresponding to stress levels. Users can qualitatively assess stress distribution through the viewing screen and quantitatively determine the retardation values.
