ActiveTest methods of colourless optical glass—Part 7: Extent of striae
无色光学玻璃测试方法 第7部分：条纹度
Application Summary AI generated
This standard specifies the test method for determining the extent of striae (internal thread-like defects) in colourless optical glass. It is applied in the manufacturing and quality control of optical components, such as lenses and prisms, used in cameras, telescopes, and other precision optical instruments. The test ensures that glass blanks meet the required homogeneity standards for high-performance optical systems.
