ABSTRACT:
Illumination and imaging subsystems for a system for inspecting ophthalmic lenses. The subsystems include a lens holder, a light source, a pixel array and a processor. In use, the light source generates light pulses that are transmitted through the lenses in the lens holder and onto the pixel array to produce thereon light patterns representing the ophthalmic lenses. The pixel array generates signals representing the intensity of light thereon, and the processor processes those signals according to a predetermined program to generate an output signal representing a condition of the lens.
