Abstract
A laser level disposable on a reference surface includes a housing, a pendulum pivotably connected to the housing, a first laser diode disposed on the pendulum for emitting a first laser beam along a first path, and a lens disposed on the pendulum in the first path for converting the first laser beam into a first planar beam, the first planar beam forming a line on the reference surface.
