  • Instrument introduction:
         Through the observation of optical birefringence, the quality of optical glass, glass products or other small transparent products can be checked quickly and continuously.

    Use of the instrument:
        A stress meter is an instrument used to check the magnitude and distribution of stress in a transparent object. It is not only widely used in optical glass, optical instruments, glass products, plastic products and other industries, but also plays an important role in the inspection of safety and explosion-proof indicators of building materials, lamps, pharmaceuticals, beverages, and handicrafts. There are also many applications in science. At the same time, this instrument is also an ideal teaching and experimental equipment for colleges and universities.
