About this chapter
This chapter explains the Scheimpflug principle and when to apply Scheimpflug correction upon your ZEUS projector. In addition to
the procedure for Scheimpflug adjustment the procedure to adjust the Back Focal Length is also included in this chapter.
Scheimpflug principle
The "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 to these two planes. If, however, the lens
plane is tilted with respect to the DMD plane, the plane of sharp focus will also be tilted according to geometrical and
optical properties. The DMD plane, the principal lens plane and the sharp focus plane will intersect in a line below the
projector for downward lens tilt.
