Another great set of meetings for ISO TC172 SC1. The US hosted the meetings at NIST Gaithersburg,outside of
Washington D. C .We made great progress on the German initiative to incorporate generalized surface
descriptions for freeform optical surfaces into the standard, as well as some healthy discussions on new ways to
create tabulated drawings. We also discussed how to move forward with an overhaul of the surface imperfection
standard, hopefully to create a grand, unified surface imperfection standard!
