Latest Patents
One of his latest patents is titled "Depth of field enhancement for optical comparator." This invention involves an optical device inspection system and method that employs a narrow aperture on a magnifying objective lens. This design reduces the circle of confusion and increases the depth of field, allowing for simultaneous focus on all portions of objects being inspected. The use of an arc lamp with an elliptical reflector, combined with a condenser lens, focuses a more intense beam of light through the objective lens. This innovation provides sufficient brightness without sacrificing any depth of field.
Another significant patent is the "Ophthalmic lens transportation and inspection cell." This invention describes a method and apparatus for an inspection cell that allows contact lenses to be presented in a known orientation for inspection. The cell can be tipped to place the inspected lens into a known pick-cup location upon passing inspection, or it can discard the lens if it does not pass. The automation of this process can be easily controlled by selecting the rate at which the cell is tipped.
