Abstract
A lens system which compensates for various aberrations, including chromatic aberration, with an enlarged field-of-view. The lens system includes a positive element and a negative element, each positioned in an optical path of incident light. The positive element includes a first negative lens, a convex lens and a hologram optical element. The negative element includes a second negative lens.
