Abstract
A method and apparatus for an inspection cell that allows contact lenses to be presented in a known orientation to an operator or vision system for inspection. The cell can be tipped to allow the inspected lens to be placed into a known pick-cup location upon passing inspection, or if the lens does not pass inspection, it can be discarded. The placement or discarding of the lens can be readily automated by selecting the rate at which the cell is tipped.
