Take into account that the lens focus may slightly drift while the lens is warming up from cold to operation
temperature. This is a typical phenomenon for projection lenses used with high brightness projectors. The
operation temperature of the lens is reached after approximately 30 minutes projection of average video.

What has to be done ?
The lens holder has to be adjusted so that the “sharp focus plane” of the projected image falls together with the plane of the screen
(Fp1
→
Fp2). This is achieved by changing the distance between the DMD plane and the lens plane (Lp1
→
Lp2). The closer the lens
plane comes to the DMD plane the further the sharp focus plane will be. It can sometimes happen that you won’t be able to get a
complete focused image on the screen due to a tilt (or swing) of the lens plane with respect to the DMD plane. This is also known
as Scheimp
fl
ug’s law. To solve this the lens plane must be placed parallel with the DMD plane. This can be achieved by turning the
lens holder to remove the tilt (or swing) between lens plane and DMD plane (Lp3
→
Lp4).

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.
