In the visible region the dispersive power
WebThe Sellmeier equation is a later development of Cauchy's work that handles anomalously dispersive regions, and more accurately models a material's refractive index across the ultraviolet, visible, and infrared spectrum. Humidity dependence for air. Cauchy's two-term equation for air, expanded by Lorentz to account for humidity, is as follows: WebThe dispersive power of a material is defined by the index difference taken over a given wavelength range divided by the mean refractive index minus one. Thus, in the visible part of the spectrum, the dispersive power of a glass is defined by Dispersive power = = (TIF -- nc)/(nD -- 1) where wavelength C = 0.6563 , D = 0.5896 , and F = 0.4861 .
