Due to uneven cooling or other reasons such as mechanical action, transparent objects will generate internal stress and cause birefringence. The crystalline substance itself has the optical characteristic of birefringence. The WYL-4 stress birefringence instrument adopts the principle of polarization photoelectric vector synthesis and optical compensation, and determines the size of the stress birefringence of the sample by quantitatively measuring the optical path difference of the sample. This instrument can accurately measure the optical path difference of the optical wave plate and determine the stress level of the optical glass. It is an indispensable instrument in the optical instrument manufacturing industry and an important tool for the study of crystal minerals.
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.
