Abstract
An optical inspection system comprises an optical system for providing an image of an object being inspected. The optical system comprises a plurality of lenses arranged along a normal optical axis, one of the lenses including an objective lens. A collimated laser beam is directed to one edge portion of the objective lens toward the object to illuminate the object with a spot. A focus lens focuses the spot reflected from the object and transmitted through an opposite edge portion of said objective lens onto a linear detector, whereby the location of the spot on the linear detector provides the position of the object above or below a reference plane.
