Product introduction
WYL-3 dial instruments are used to stress birefringence measurement of transparent object due to the internal stress. It has two functions of quantitative and qualitative, simple and convenient operation, very suitable for industrial applications.?
????
This kind of stress (birefringence) of the source, is caused by uneven cooling or external mechanical effects and other reasons, it directly affects the quality of optical glass, glass products, transparent plastic products. Therefore, stress control is a very important part of the production of optical glass, glass products, etc. in the process of transparent plastic products. The stress meter can be qualitative or quantitative identification of products through the observation of stress (DUT) quality, has been widely used in optical glass, glass products, transparent plastic products rapidly, a large number of tests, to solve the complex problem in fact not through mathematics.?
