The possibility of converting the continuous refractive-index profile into a two-index solution is shown. The technique of conversion that is developed makes it possible to take dispersion into account. This ensures that it is possible to achieve a good agreement between theory and practice in a broad spectral range. Several gradient-index filters have been developed and produced, and measuring results are presented.
