Abstract

A system for inspecting ophthalmic lenses and including transport, illumination, imaging and image processing subsystems. The transport system moves a multitude of ophthalmic lenses along a predetermined path to move each of those lenses, one at a time, into a lens inspection position, and the illumination subsystem generates a series of light pulses and directs a respective one light pulse through each ophthalmic lens. The imaging subsystem generates a set of signals representing selected portions of the light pulses transmitted through the ophthalmic lenses, and the image processing subsystem receives those signals from the imaging subsystem and processes those signals according to a predetermined program to identify at least one condition of each of the lenses.
