Abstract

The filament in lamps used in document scanning devices must be presently positioned relative to the reflector. Added complications are presented due to the fact that in many commercially available lamps, the filament in the lamp is not uniformly positioned relative to the external surface of the bulb. Thus, each bulb must be individually aligned relative to the reflector in order to achieve optimum performance.
