Patent ID: 6892463

Claim:
A device capable of producing two mutually perpendicular laser beam planes comprising: a) at least one laser module emitting an irradiated light beam and having: i) a semiconductor laser emitting a diffused light beam; and ii) a focusing system focusing the diffused light beam and emitting the irradiated light beam; b) at least one optical deflector deflecting and splitting the irradiated light beam into two perpendicular light beams, each of the at least one optical deflector includes a prism and an optical wedge correcting a transmission declination resulting from a refracting surface of the prism; and c) two light beam expanders, each of the two light beam expanders has a conical shaped interior and hollow electric motor, each of the two light beam expanders expanding one of the two perpendicular light beams into one of two perpendicular optical planes.
