Micro-crack is one of the most effective factor to the intensity and service life of optical components. Owing to the micro-crack on surface  actual strength of optical components is reduced severely  even less than ten-percent of its theoretical strength. According to fracture mechanics  the mechanisms of the formation and propagation of micro-crack and the growth theory of sub-critical micro-crack are discussed in the paper firstly. Based on practice  an on-line test method disposing etching holes-the molecule-infiltrating method and the principles of acid-etching method disposing micro-crack are described. Followed by the demolishing mechanism of abrasives and a more reasonable removal redundancy of fine-grinding and polishing during  optical production is given by using abrasives in different-size orderly. 2009 SPIE.
