A Polarimeter is a valuable optical instrument used to observe and analyze stress within transparent materials. By detecting retardation and calculating stress in birefringent materials under polarized light, it provides critical insights into material properties. Its application enhances manufacturing quality control to ensure material integrity and performance, optimizes manufacturing process which results in stronger and more reliable products, and supports cutting-edge research and development from aerospace to consumer electronics application.

APPLICATIONS OF POLARIMETER

Stress Analysis in Transparent Materials

Polarimeters are used to identify stress points, measure stress retardation and glass temper number, allowing for corrective measures to be taken before products reach the market. Polarimeters also help in identifying internal stress in plastic components, which can affect durability and performance.

Research and Development

By understanding the stress presence and behavior of materials under different conditions, researchers can identify potential applications and improve material formulations. This can lead to innovations in material science and engineering.

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.

How a Polarimeter Works?

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.

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.
