Abstract
An optical system for projecting an alignment marker on to a workpiece relative to the circular blade of a power saw. The light projection system projects a planar beam of light along a plane defined by one side of the blade to designate the location at which that side of the blade will enter the workpiece. An adjustment mechanism may be included to allow movement of the light projection system so that the planar beam of light can be selectively located parallel to the plane defined by either side of the blade.
