Accessories are disclosed for use with a laser tool which may or may not be self-leveling. The accessories include one or more diffraction elements, effective to receive the incoming beam and produce a plane of diverging laser beams. In preferred embodiments the diffraction elements are self-leveling. When the diverging beams are directed against a surface such as a floor, wall or ceiling, a series of discrete spots define a visible reference line useful in construction layout. The spots themselves may each locate the position of a fastener to be installed, for example, by giving the approximately correct spacing for reference of the user. In another embodiment, lenticular arrays are used to create beams which diverge in a plane and overlie one another to form a visible reference line on a wall or other surface. The line preferably is plumb or level and in one embodiment the user can select among two or more arrays to form a plumb or level line of selected length.
A method used in construction layout for producing and using a visible reference line on a surface, the line being substantially level or plumb, comprising:
A system for producing a visible reference line on a surface, formed from a laser beam, the reference line being substantially level or plumb in orientation, comprising:
An apparatus for producing from a laser beam a visible reference line on a surface, comprising:
