Dispersion is a description of the variation of the refractive index with wavelength. It is specified using the Abbe number, v d, defined as (n d - 1)/(n F - n C) where n F and n C are the refractive indices at 486.1nm (Hydrogen F-line) and 656.3nm (Hydrogen C-line). A low Abbe number indicates high dispersion.
