Side by side laser level device

摘要

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.
