Abstract
The paper presents a mathematical apparatus based on the requirement of preserving tautochronism in each of the diffraction orders of a harmonic kinoform lens. The apparatus was used as the basis of a method for calculating the lens microstructure.яThe method limits the relative longitudinal chromatism of the lens to a given level and provides the initial parameters necessary for the radial calculation and optimization of the optical system with a harmonic kinoform lens using well-known commercial optical design computer programs
