Abstract

See full text

An optical assembly includes a Fresnel lens and a diffractive optical element. The Fresnel lens includes a high-refractive-index material having a refractive index greater than 1.9. The diffractive optical element is optically coupled with the Fresnel lens to compensate for chromatic aberration caused by the Fresnel lens. A method for imaging light with the optical assembly is also disclosed.
