mil-prf-13830bscratch and dig

Surface imperfection specifications (i.e. Scratch-Dig) are among the most misunderstood, misinterpreted, and ambiguous of all optics component specifications. This course provides attendees with an understanding of the source of ambiguity in surface imperfection specifications and provides the context needed to properly specify surface imperfections using a variety of specification standards, and to evaluate a given optic to a particular level of surface imperfection specification. The course will focus on the differences and applications of the MIL-PRF-13830, ISO 10110-7, and ANSI/OEOSC OP1.002. Many practical and useful specification examples are included throughout, as well as a demonstration of visual comparison evaluation techniques and artifacts.
