Adjust Left/Right Boresight - Christie Solaria CP2220 User Manual

Appendix A: Intelligent Lens System
A.2.2 Adjust Left/Right Boresight
The goal for left/right boresight alignment is to adjust the lens mount
until both sides of the image focus on the screen simultaneously.
Projectors are aligned properly at the factory, but due to mechanical
tolerances in the alignment between the projector and the screen, the
left and right sides of the image come into focus at different times. By
focusing on the left side of the screen, we need to determine if the
right side of the image focuses in front or behind the screen relative to
the left side. NOTE: Use a test pattern with a single pixel vertical
and horizontal line and perimeter frame such as DC2K Framing or
RGB Alignment.
1. The Horizontal Hold Screw acts as counter-resistance to hold the
lens mount in place once set. Before adjusting the boresight,
loosen the Horizontal Locking Screw. See Figure A-3.
2. Extend the lens focus completely.
3. Adjust the Focus to retract the lens using the
A-4). Watch the image at the left edge of the screen until it comes into focus. If the image appears well-
focused on the left edge but not on the right, we need to determine if the right side focuses in front of or
behind the screen. If the entire screen come into focus, skip to step 7.
