Polariscope

When observing a sample through a polariscope, if you observe the color difference between the sample and the background, it indicates stress presence within the sample. Uniform stress patterns indicate balanced stress distribution, non-uniform patterns indicate varying stress levels.

They differ in using purpose and operation methods.

A strain viewer is primarily used for visualizing stress patterns, while a polarimeter provides quantitative measurements of stress retardation and glass temper number. A strain viewer relies on the visual observation of interference patterns, whereas a polarimeter measures analyzer rotating angle or phase difference of polarized light.

① Do not clean the sample stage with water;

② Do not place the device under direct sunlight;

③ Do not place damp objects on the sample stage;

④ Do not place overheated or cold objects (> 80℃, < 20℃) on the sample stage;

① Electrical Safety: Ensure all cords are intact and avoid contact with water to prevent electrical hazards.

② Stable Surface: Place the strain viewer on a stable, flat surface to prevent it from falling down and causing accidents.

③ Handle with Care: Handle the strain viewer and samples carefully to avoid damage or injury from sharp edges or broken pieces.
