Optical coating standards

Robert E. Parks

It has been some months since we last discussed the work of ISO/TC 172/SC 3/WG 2, Optical Coatings. In that time Karl Guenther has moved from Balzers in Europe to a position with the Center for Applied Optics at the University in Huntsville. In Europe, Guenther was active in the work of SC 3/WG 2; since moving to the U.S. he has been elected to the head of WG 2. He and his international committee are now working on revisions to an ISO/Draft Proposal 9211, Optics and Optical Instruments- Optical Coatings, Part 1-General.
