Patent ID: 6951411

Claim:
A light beam generation and focusing device for directing at least one focused beam of light at a target surface plane, said device comprising: a light source constructed and arranged to emit at least one beam of light; and a lens assembly constructed and arranged to focus said at least one beam of light on the surface plane; said device being constructed and arranged to sequentially direct the at least one beam of light to at least two spaced locations on the surface plane including at least one rotating wedge interposed in the path of said light beam capable of redirecting the beam to multiple locations and actuate said light beam when said wedge is in position to direct the beam to said target; said light source comprising at least two laser diodes mounted on a mounting block and wherein said mounting block includes at least two generally planar walls generally orthogonal to the target locations, and that the spacing between said walls generally fixed the relative spacing between the targets of the diodes.
