Abstract
A laser beam target for use with a projector capable of providing a reference laser beam of light traveling in a predetermined path is provided and includes a main body portion having first and second surfaces. A plurality of projections are provided on at least one of the first and second surfaces for directing at least a portion of the reference beam of light into a specific range of vertical viewing angles away from the path of the beam as the light passes from the body, thereby permitting a worker viewing the target to more easily determine when the reference beam of light is in alignment with appropriate reference indicia on the target.
