Abstract: Surface elements for the face of laser beam targets which more efficiently use the properties of light reflectance and absorption to aid a laser tool operator in accurately directing a laser's beam. The surface elements include beam alignment crosshairs and a background. A light-reflective material makes up or covers the background areas of the face not occupied by the beam alignment crosshairs, and allows the operator to better determine the direction and amount of lateral or vertical movement required for final alignment. The beam alignment crosshairs on the face of the target are formed from non-reflective, light-absorbing material that gives the beam an appearance of vanishing when precisely centered. Coupled with the light-reflective background, the light-absorbent crosshairs remedy multiple detriments from beam spread at greater distances, a weak beam, and a poorly discerned beam from bright or sunlit environments.
