Abstract
A device for inspecting an object for defects and debris having a first light and a second light to create two images of the object, and a system of mirrors and lenses to direct the images to a sensing station, typically a video camera. A first embodiment uses two sources of light, a first parallel annular bundle and a second diffuse source, to inspect an open holder, such as an aluminum can without a lid, for defects and debris. A second embodiment uses two sources of diffuse light to inspect a cylindrical glass tube, such as a fluorescent light bulb, for defects and debris.
