9. Adjust the fold mirror until either the top left edge or the bottom right edge of the illumination
spot becomes visible on the DMD.
10. Adjust the integrator rod Focus paddle to optimize focus for one of the following:
•
Along the top edge of the image, approximately one-third across the image from the left.
•
Along the bottom edge of the image, approximately one-third across the image from the
right.
11. Adjust the fold mirror to center the image on the DMD array.
12. Use the integrator rod Zoom paddle to increase the zoom until the entire active area is filled,
with no dark areas at the edges or corners.
Ensure that overfill is minimized to improve DMD life and system optical efficiency for
brightness.
13. Once the adjustments are complete, tighten the lock screw for the Zoom and Focus paddles,
and the two fold mirror screws.
14. Close the access door for the Zoom and Focus paddles.
Adjusting the boresight
A boresight adjustment balances the tilt of the lens mount to compensate for screen-to-projector tilt.
