1.Observation range and sample size: The observation range is the range of the field of view, and the sample size can be larger than the range of the field of view. As long as the observed part can be placed in the field of view, it can be observed

2.Measurement unit: If the degree is in degrees, you can multiply it by a coefficient and convert it to nanometer values yourself

Product Features

·WYL-3The dial stress gauge is an instrument used to measure the birefringence phenomenon caused by internal stress in transparent objects.

·It has both quantitative and qualitative functions, with simple and convenient operation, making it very suitable for industrial applications.

·The source of this stress (birefringence) is caused by uneven cooling or external mechanical effects, which directly affects the quality of optical glass, glass products, and transparent plastic products.

·Stress control is an extremely important part of the production process for optical glass, glass products, transparent plastic products, and other materials.

·This stress gauge can qualitatively or quantitatively identify the quality of products (test pieces) by observing stress, and is widely used in the industries of optical glass, glass products, and transparent plastic products for rapid and large-scale inspection, solving complex problems that cannot be solved through mathematical operations in practice.
