Summary
This document specifies the measuring method for the refractive index of optical glasses with the
accuracy within 1 × 10-5
used in the spectral range from 365 nm to 2 400 nm.
Additional information on how to apply the refractive index in the dispersion and the various dispersion
formulae of optical glasses is given in Annex A and Annex B.
