•If you are using Hikari glasses, be sure to use this glass catalog update with CODE V 10.2 SR3. Hikari recently extended the Laurent's dispersion equation to include more terms than the traditional form. The computed refractive indices for glasses including nonzero values for these new terms will only be correct in CODE V 10.2 SR3. If you utilize this GLASS.CAT with older versions of CODE V, and request one of these new glasses, the refractive indices computed by CODE V will be incorrect. pJ ;J>7Gt
