In previous years, this committee reported on the need for a US National Laser damage standard, addressing the needs of domestic industry. In 2017, a process was reported that connected the measurement of the active defect density in a small area, a, with the likely density of such defects over a larger area, A. This was presented as the basis of a Type 1, go/no-go test. 2018’s achievement, is development of process starting from a user’s requirements and flowing into test parameters. This year’s report covers the resulting test procedure that implements the test process a useful workable standard. |
