  • Computerized Polariscope

    • Place of origin:  

      China

    This Polariscope adopts automatic Senarmont method to measure the internal stress in transparent objects . In the previous manual Senarmont method, the observer needs to determine the relatively brighter part and relatively darker part by their eyes, thus operation errors can not be prevented . This device automatically detects the image luminance, thereby finding the relatively darker part

  • Preform Strain Viewer ( Polariscope)

    • Place of origin:  

      China

    Measuring principle The internal stress of plastic products has a birefringent characteristic. In other words, if there is stress inside of these types of products, light from he polarized lamp will be divided into different units, which produces optical interference phenomenon (ripple patterns) in turn. When the plastic preform is placed on the sample plate at 0°or 90°, the colored birefri

    patterns, you can see stress distribution directly, then evaluate and improve the molding process. The inspection of plastic molds is complex as the colored patterns cased by stress is irregular. For example, a qualified mold will have a large amount of stress released by tension.
