ABSTRACT:
Light deflection apparatus is provided for use with apparatus for uniformly illuminating a planar original in which light rays emanating from a flash lamp are blocked from directly striking the original. The deflection apparatus includes a plurality of elongated reflective louvers juxtaposed in the path of direct light rays to deflect the rays along a predetermined path. A planar reflector positioned adjacent the original in the path intercepts and reflects the light rays upon and illuminates the original.
