4. Computerized Polariscope Stress Magnifier Measuring Stress Value In Glass And Crystal Products
 In the previous manual Senarmont method, the observer needs to determine the brightest point and the darkest point by their eyes, thus operation errors can not be prevented . This device automatically detects the image luminance, thereby finding the darkest point precisely . By inputting sample photoelastic constant and thickness in advance , the stress value will be calculated by the computer . In addition, Sensitive Color method is used to clearly define the direction of stress.

Strain Viewer Detecting Stress In Crystal , Lense And Prism
Different from common bench type Polariscope , this handheld Polariscope adopt seperating design , that means the analyzer and polarizer are movable . In this way , the net weight is almost reduced to half . This lightweight design make 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.

Automatic Surface Stress Meter Detecting Stress Value And Stress Depth In Chemically Tempered Glass
The surface stress meter ( Ref. ASM-200-FAP)measures surface stress of tempered glass and the depth of the stress layer according to photoelastic technology by letting light spread along the glass surface. This machine is equipped with a PC, which can reduce measurement errors caused by the operators . Moreover, it is more convenient for the management of testing data. Thickness Gauge is optional to improve the measurement efficiency.
