The automatic compensation method (Senamon) was used to quantitatively measure the internal stress of the transparent body. In the previous manual compensation method, the observer needed to rotate the graduated compass to determine the brightest position and the darkest position, so it was easy to cause errors.
This device automatically detects the brightness of the image, thereby reducing human error. Equipped with a zoom lens, it can also detect small-sized samples. Equipped with a computer to save measured data and images.
In addition, it can also be detected by photochromometry to make the direction of stress more clear.
Features: Reduce human error
Input the photoelastic coefficient and depth of the measurement object in advance, and the stress level can be automatically calculated
