Abstract
A laser reference device includes at least one planar or flat surface and an internal laser light source for generating a laser light beam. A lens inside the device may convert the laser light into a fan-shaped beam, and project the beam adjacent the planar or flat surface of the housing. The fan-shaped beam thus projects along that surface of the housing. If the laser leveling device is placed with the flat surface on a table or floor, for example, the fan-shaped beam will be in a level plane. This allows a user to place the laser leveling device on a surface and generate a laser light to align surfaces or objects, such as objects on a wall.
