Handheld Polariscope ( Strain Viewer )

 

The handheld Polariscope ( Ref.PSV-202-DL ) has been designed to cover a wide range of strain viewing applications.

It can be applied to the quality control inspection of glass and plastics components and may be employed as a vertical or horizontal viewing instrument.

Different from common bench type polariscope, this handheld Polariscope adopt separating design, that means the analyzer and polarizer are movable. In this way, the net weight is almost reduced to half. This lightweight design makes it more convenient to carry.

The working space available within the unit enables a wide variety of components to be accommodated for hand held examination under polarizing light, such as fish tank.

Measuring Principle

The internal stress of glass and plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light from the polarized lamp will be divided into different units, which produce optical interference phenomenon (ripple patterns) in turn.

Under white-light lamp, you can see aubergine ripples,  which is caused by the presence of stress. 

From the observation of colored patterns, you can see stress distribution directly, then evaluate and improve the annealing process.

The inspection of plastic molds is more complex as the colored patterns caused by stress is irregular. A similar situation may occur with glass products, which is called stress stretching. For example, a qualified mold will have a large amount of stress released by tension.
