Abstract
A laser level generates an emitted laser beam and a cross laser beam plane. The laser level includes a frame, a pendulum pivotally mounted to the frame to rotate about two axes with respect to the frame in a manner such that the gravity center of the pendulum defines a plumb line along the gravity direction, a laser module provided in the pendulum to generate a laser beam that is transmitted along a transmission line in a direction perpendicular to the plumb line, a spectroscope provided in the pendulum along the transmission line of the laser beam to split the laser beam into a split beam and an emitted laser beam that is perpendicular to the split beam, and a cross lens provided along the transmission line of the split beam in the pendulum to transform the split beam into a cross laser beam plane.
