Abstract
An unsymmetrical elliptical reflector for spatial illumination. The invention includes a novel reflector and a novel illumination system including the novel reflector. The novel reflector includes first and second, non-symmetrical, elliptical elongate reflector surfaces. The eccentricities of the first and second reflector surfaces are different such that they have common first foci and different conjugate foci. The novel illumination system incorporates the novel reflector and provides intense, focused illumination at two foci positioned at two heights above a conveyor surface. The illumination intensity between the two foci is sufficiently intense to provide adequate illumination of encoded labels carried on package surfaces at heights between the two foci.
