Abstract
A color imaging assembly for forming spatially separated, color component images of an object on a unitary image plane, comprising an imaging lens adapted for receiving a polychromatic imaging light beam from the object for imaging the object on the unitary image plane; a unitary multilayered beam splitter disposed obliquely in the path of the polychromatic, imaging light beam for splitting the polychromatic light beam into a plurality of parallel, spatially separated, color component beams having optical axes positioned perpendicular to the unitary image plane; and a path length compensator device disposed between the beam splitter and the unitary image plane for refractively compensating for differences in optical path lengths of the plurality of color component beams whereby each of the color component beams provides a focused color component image of the object on the unitary image plane is disclosed. A beam combiner assembly having a component beam path length compensator device is also disclosed.
