    摘要: An optical comparator in which images of a master component and a sample component are inspected by comparison of the images that are projected in a moving, abutting, merging, mirror image, a limited area of the components being viewed in a scanning illumination at a controlled rate for full viewing coverage. The components are held in a sliding tray with means for rapidly changing the component to be inspected, while maintaining precise alignment. A closely directed light source and efficient cooling device permits prolonged operation of the apparatus, and instant access to mark defective portions of the component is provided, without interrupting viewing. The location of each defective portion is marked on a reference chart for use in a viewer which provides a composite image of the chart and component in proper registration for easy identification of the faults.
