ABSTRACT:
The illuminator includes a housing having thereon a transparent work supporting stage overlying an opening formed in the top of the housing. A plurality of light sources in the housing emit an array of spaced, parallel light beams through a like plurality of collimating lenses which collimate each of the beams emitted by the sources. The collimated light beams pass through a light transmissive diffuser which is interposed in the housing between its opening and the collimating lenses, which homogenizes the collimated light beams produced by said lenses. The homogenized light then passes through the housing opening, either directly or via one or more reflective surfaces, onto a workpiece located on the stage. In certain embodiments the collimated light beams pass through a beamsplitter before passage through the diffuser.
