GSO ISO 7944:2007 Scope
This International Standard specifies two reference wavelengths to be used for the characterization of optical
materials, optical systems and instruments, as well as ophthalmic lenses. It defines the associated principal
refractive indices and principal dispersions, as well as the Abbe numbers with regard to these reference
wavelengths and principal dispersions.
