Abstract
Diffractive lenses have recently become realizable elements in optical systems. However, their application to wide band optical imaging systems are limited because they are highly dispersive and exhibit unacceptable amounts of color related aberrations. In this paper we will present a design study of the achromatization of hybrid refractive-diffractive lenses over wide spectral bands. Design examples of hybrid lenses which operate in the visible, mid-infrared (3 - 5 micron) and long-wave infrared (8 - 12 micron) spectral bands will be presented and a comparison with conventional lenses designed to operate in these spectral bands will be discussed.
