ABSTRACT:
An achromatic imaging system employs a diffractive hologram as the primary element. A conventional achromatic optical element, comprising either a refractive lens or mirror, is positioned between the primary element and a second holographic optical element. The holographic and conventional elements combine to form an imaging system characterized by high resolution and light weight.
