Paper Abstract

The index of refraction is a measure of the speed of light in matter. The dispersion, or change of the refractive index with wavelength, can be represented mathematically many different ways for use in optical design. What is covered in this paper is not what the index of refraction is, but how it is represented and how well it is represented over the transmission band of a material. More specifically, the emphasis of this paper is on how the dispersion characterization of a material (particularly in the infrared) effects the chromatic performance of a lens design and the development of a refractive-index interpolation fit criterion based on dispersion.
