ABSTRACT:
A device useful for illuminating parts to be inspected includes an illumination device employing a plurality of bundles of optical fibers coupled with a light source. The device includes a housing having an optical lens in one end which has an outer surface that is convex about a single axis. A clamp assembly mounts the bundles on the opposite end of the housing, with the ends of the bundles extending through a rectangular opening in an end wall of the housing. An aperture plate between the lens and the ends of the bundles masks light from the bundles so that all of the light passing through the aperture plate falls on the lens, thereby partially collimating the light impinging on the inner face of the lens.
