About this chapter
This chapter explains the Scheimpflug principle and when to apply Scheimpflug correction upon your DP2K-
SLP Series. 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.
