7. When the left/right
boresighting is complete,
focus the image at the
top edge of the screen
(Figure 2.48).
If the bottom remains
blurry while the top edge
is focused, refer back to
Step 2 but use a 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,
skip to Step 11.
8. Adjust the vertical boresight bolt (Figure
2.49) using one 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.

should now be in focus, the center of the

Refocus at center of image. The goal is good focus at center and on all sides.

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.
