Abstract
A refractive component includes at least one reflection surface and at least one diffractive optical element. The refractive component is configured to receive a light beam and the light beam expands within the refractive component and is reflected by the at least one reflection surface. The diffractive optical element is configured to receive the light beam reflected from the at least one reflection surface, collimate the light beam, and redirect the light beam out of the refractive component.
