A laser level includes a pair of level units arranged side by side and disposed
in different oriented directions. Each laser level includes a laser light source
adapted to emit a laser beam, a beam splitter adapted to simultaneously split the
beam into first and second light beams along perpendicular first and second directions,
and a first and a second aspheric-cylindrical lenses respectively arranged in the
first and the second directions. The first and the second aspheric-cylindrical
lenses have two optical axes respectively extending along the first and second directions.
