Buchdahl's glass dispersion coefficients calculated in the near infrared
Abstract:
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 microm are listed. When evaluating Buchdahl coefficients across different wavelength ranges (i.e., infrared or ultraviolet), the chromatic coordinate constant alpha can be changed to improve convergence of the refractive-index model.
