AbolishedColourless optical glass test methods--Examination method for extent of stria
无色光学玻璃测试方法 条纹度检测方法
Application Summary AI generated
This standard specifies a method for detecting and grading the extent of stria (string-like inhomogeneities) in colourless optical glass. It is applied in the quality control and acceptance testing of optical glass blanks used in lenses, prisms, and other precision optical components. The method ensures that glass meets the required homogeneity standards for applications in cameras, telescopes, microscopes, and other optical instruments.
