Buchdahl’s chromatic coordinate provides a rapidly converging polynomial form for describing the dispersion of glass. A method of generating Buchdahl’s chromatic coordinate coefficients with a Code V sequence file is presented. The quadratic model coefficients for eighty-two glasses at a base wavelength of 0.830 μm are listed. When evaluating Buchdahl coefficients across different wavelength ranges (i.e., infrared or ultraviolet), the chromatic coordinate constant a can be changed to improve convergence of the refractive-index model.
