title: Diffractive-refractive hybrid corrector for achro- and apochromatic corrections of optical systems.
abstract: The possibility is shown of achro- and apochromatic correction of an optical system with any residual chromatism by completing the system with a diffractive-refractive hybrid corrector comprising one diffractive lens and one or two refractive lenses.
