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.
REFOCUS
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, and check boresight again.
