Convergence test pattern
Work Instructions:
•
GREEN and RED DMD’s are to be adjusted with reference to the BLUE dmd.
•
Each adjustment allows for approximately 10 pixels maximum displacement to either side of the nominal BLUE position
•
Rotation is limited to approxi/- 5pixels on the left screen
fl
ank and +/- 5 pixels on the right screen
fl
ank
•
One turn of an adjustment screw relates to an approx. 5-pixel displacement on the screen.
Take Care:
•
In rare cases it can happen that the nominal dmd position falls within a
dead zone
, where the mechanism changes from a
pushing to a pulling function. This dead zone is due to inherent tolerances within the mechanism. Approximately 2 turns are
required to get out of the dead zone. If it so happens that the nominal position of an adjustment falls within this dead zone,
it is preferable to continue screwing through the dead zone for another 2 turns. Then return to the required nominal position.
The dead zone should now be displaced away from the required end position. The DMD is now securely held in the nominal
position.
•
Each adjustment is limited to approximately 10 pixels displacement. DO NOT try to force the adjustment beyond this point. The
system has an end of travel in both directions, but with excessive force one could cause damage.
