Adjusting Left/Right Boresight; Lens Mount Vertical Boresight - Christie Solaria CP2210 Setup Manual

Section 2: Installation and Setup

2.8.2 Adjusting Left/Right Boresight

The following section outlines the vertical and horizontal boresight adjustments for the lens mount. When
performing these adjustments, the goal is to balance the tilt of the lens mount to compensate for screen to
projector tilt, but also to precisely maintain the original factory settings of the lens mount axial position.

optimal lens performance (i.e. factory setup of absolute lens distance to the prism). It is
critical that each turn of the cap screws are tracked to ensure adjustments are accurate.
1. It is recommended that top/bottom boresight be completed before horizontal boresight. NOTE: Typically,
horizontal boresight does not require adjustment. It should only be adjusted if a large horizontal angular
offset to the screen is required.
2. Select an appropriate test pattern for boresight adjustments, via the TPC by clicking the Test Patterns
button from the Main Panel. This will launch a collection of test patterns predefined in the Administrator
Setup: Preferred Test Pattern Setup window. It is recommended to use the DC2K Framing test pattern.
3. Use a 5mm hex key to loosen the set screw (Figure 2-17/B).
4. Use the 5mm hex key to turn the vertical adjust cap screw 1/8 of a turn counter-clockwise. (Figure 2-17/
A).
5. Adjust both left and right horizontal adjusters by half the number of turns, in the opposite direction of the
vertical adjust (). For example, if the vertical adjust cap screws was turned 1/8 of a turn, the left and right
horizontal cap screws should be turned 1/16 of a turn in the opposite direction.
6. Check the screen. If the projected image is worse than before the adjustment was made turn the vertical
adjust cap screw 1/8 of turn clockwise. Ensure the left and right horizontal adjusters are adjusted equally in
the opposite direction to correct axial focus. NOTE: The 1/8 of a turn is a suggestion only and can be less
if needed; however, it should never be exceeded. Always compensate both left and right horizontal
adjustments according to the vertical adjustment.
7. Always observe the screen after each adjustment. If necessary, continue to make adjustments until both top
and bottom are equally sharp. Remember to adjust left and right horizontal adjusters in the opposite
direction each time. This ensures the lens is in the same relative position.
