Abstract
A lens inspection method and apparatus comprising a pallet having wells for receiving one or more lens containers at the receiving point. A conveyor achieves uniformity of pallet motion when transporting the lens. The pallet wells includes holes that pass through the pallet. These holes, along with a side driven transport system, make possible an arrangement of a lamp and camera on opposite sides of the lens for capturing an image of a lens. A computer implemented algorithm processes the digitized image to determine the acceptability of the lenses. A lens disposition mechanism uses a signal generated by the computer and indicates lens acceptability to disposition the lens by physically separating a container with an acceptable lens from an unacceptable lens. After disposition of containers, the pallet is returned by conveyor to the lens receiving point.
