Adjust Top/Bottom Boresight - Christie CP2000 Setup Manual

Section 2: Installation and Setup

ADJUST TOP/BOTTOM BORESIGHT

7. When left/right boresight is complete, focus the
image at the top edge of the screen (Figure 2-41).
If the bottom remains blurry while the top edge is
focused, refer back to Step 2, but place the paper
at the bottom of the screen to determine whether
the bottom of the image is focused in front of the
screen or behind the screen. If the bottom is well-
focused, proceed to Step 11.
8. Adjust the vertical boresight bolt (Figure 2-42)
using an Allen key to hold the bottom hex screw and another
to turn the adjustment bolt above it. Adjust as necessary to
direct or "aim" the lens toward the edge of the image, which
focused too close to the lens. When both top and bottom
appear equally blurry, re-focus at the top of the screen.
9. Adjust vertical offset to re-center the image on the screen.
10. Repeat Steps 8 and 9 until the top and bottom of screen are
both well-focused.
11. Although all sides of the image should now be in focus, the
center of the image will be slightly blurry at this point.
Refocus at center of image. The goal is good focus at center
and on all sides.
12. Adjust the "hold" screw to lock in place. Recheck boresight.
If present, swing the anamorphic lens in position in front of the
primary lens. It should magnify in the horizontal direction only,
stretching the image straight across the screen—this requires that its aperture (visible within the lens)
be vertically aligned with the screen. If the image appears skewed, loosen the locking ring on the
anamorphic lens and rotate the lens as necessary until the wide image is horizontal.
FOCUS PRIMARY LENS:
The goal is good focus at center and on all sides.
FOCUS ANAMORPHIC LENS:
anamorphic lens too—rotate its barrel as needed.

With the anamorphic lens in place, re-focus the primary lens using focus knob.
