  • The reasons which effect on the surface quality of vitreous optics was investigated and the surface micro-crakes were regarded as a main source that could change the surface strength. The causes of the surface micro-cracks were analyzed based on the mechanical grinding and forming process, then, the crack tip stress concentration and the Griffith energy balance theory were used to analyze the crack propagation mode. Combined with the surface structure defect theory and grinding crafts, the removal mechanism of micro-cracks and the effect of HF etching method were described. Finally, the methods to enhance glass strength by manufacture technology were proposed, which focus on the some surface processing, such as ion exchanging, coating and HF eting. It suggests that the HF etching would be more suitable for the removal of surface micro-cracks in processing the vitreous optics..
