Yea or Nay on Optical Fabrication, Coating Standards
Robert E. Parks
Now that the final voting on the acceptance of ISO 10110 and 9211 as international standards is complete, it's time to address the impact on the optical fabrication and coating communities. I do not yet know the outcome of the voting, but every indication is that both standards will be adopted in their entirety after some minor editorial revisions.
ISO 10110 deals with how to represent optical elements and their significant features on mechanical drawings. These features include mechanical tolerances, surface figure and finish, and centering requirements, among others. ISO 9211 covers how to represent optical coatings on drawings or specifications, and includes the coating function, spectral response, and durability.
