ABSTRACT:
An optical inspection system with an improved illumination system. The improved illumination system used to illustrate the invention has a base formed from a printed circuit board. Substrates for mounting lighting elements, which are exemplified by light emitting diodes, are formed also on printed circuit boards. These circuit boards have serrated edges and the diodes are mounted to the serrations. This configuration allows the light emitting elements to be focused on the focal point. Also in the exemplary illumination system, the light emitting elements have different beam widths so that variations in the illumination intensity as a function of elevation angle are reduced.
