Abstract
A compact laser construction instrument intended for use by the average construction contractor. The instrument is capable of generating a rotating plane of laser light and a beam of light that is perpendicular to the rotating plane. It includes a beam generator adapted to generate a beam of collimated light along a given axis. A rotating platform is provided for supporting the beam generator for rotation in a plane parallel the axis of the collimated light and about a rotation axis that is perpendicular to the axis of the collimated light in order to generate a plane of light. A means is provided that is positioned for rotation with the platform for generating a second beam of collimated light along the rotation axis to generate a rotating narrow beam of light that is perpendicular to the plane.
