ABSTRACT:
Collimated white light is transmitted through a transparent lens mold having a molded lens resting on a curved surface thereof. A telecentric lens and a camera having a digital output are used to view the illuminated lens to obtain pixel image data of the lens. The pixel image data is analyzed by a computer to detect deformities in the molded lens.
