A system and method for inspecting ophthalmic lenses. The system comprises a transport subsystem for moving the lenses into an inspection position, and an illumination subsystem to generate a light beam and to direct the light beam through the lenses. The system further comprises an imaging subsystem to generate a set of signals representing selected portions of the light beam transmitted through the lenses, and a processing subsystem to process those signals according to a predetermined program. The illumination subsystem includes a light source to generate a light beam and a diffuser to form that light beam with a generally uniform intensity across the transverse cross section of the light beam. The illumination subsystem further includes a lens assembly to focus a portion of the light beam onto an image plane, and to focus a portion of the light beam onto a focal point in front of the image plane to form a diffuser background pattern on the image plane.
