Abstract
A laser calibration device includes a housing and a pendulum pivotally coupled to the housing and suspending downwards therefrom. A laser deck is mounted to the pendulum. At least one laser for emitting a laser line is mounted to the laser deck. The laser includes a laser barrel rotatable within a barrel holder and a laser lens pivotally coupled to the laser barrel. A first adjustment mechanism is mounted between the laser deck and the laser for adjusting pitch. A second adjustment mechanism is mounted between the barrel holder and the laser barrel for adjusting roll. A third adjustment mechanism is mounted between the laser barrel and the laser lens for adjusting crowning. A fourth adjustment mechanism mounted to the pendulum for adjusting a center of gravity of the pendulum.
