DAN-403 Portable Glass  polarized stress meter

Due to uneven cooling or mechanical action ,some object will cause internal stress. The stress meter is an instrument used to check the stress and distribution of stress in a transparent object

This transparent object has the characteristics of optical birefringence. Through the transparent object, the instrument can observe the optical birefringence phenomenon, so as to quickly and continuously analyze the optical glass, glass or other transparent objects stress situation,. This machine solves the product inner quality testing problem which is hard to calculate through math method.

The main technical parameters

The instrument not only widely use in the optical glass, optical instruments, glass products, plastic products and other industrial production , but also in the building materials, lamps, pharmaceuticals, beverages, also have an important position in  the crystal jewelry system, Geology and mineral resources,etc.
