73About this chapterThis chapter explains the Scheimpflug principle and when to apply Scheimpflug correction upon the projector.Scheimpflug principleThe "plane of sharp focus" can be changed so that any plane can be brought into sharp focus.When the DMD plane and lens plane are parallel, the plane of sharp focus will also be parallel tothese two planes. If, however, the lens plane is tilted with respect to the DMD plane, the plane ofsharp focus will also be tilted according to geometrical and optical properties. The DMD plane, theprincipal lens plane and the sharp focus plane will intersect in a line below the projector fordownward lens tilt.Overview• Scheimpflug introduction• Scheimpflug adjustment• Fixation of the Lens Holder front plateR5906150 /02 XDLScheimpflug 7
