Figure 43: Prism Front/Rear Image Adjustment
To Adjust The Prism:
The prism (11) is bonded to an adjustable mount (12), which allows it to be oriented squarely to the Z-
Axis. This can correct any optical image misalignment observed during the calibration procedure,
above. Do not adjust the prism mount for any reason, unless the above calibration procedure indicates
you should do so. Slightly loosen the three socket head cap screws (8) on the prism bracket. To correct
a left-to-right image misalignment, adjust the set screws (9) to produce the desired effect. To correct a
front-to-back (top-to-bottom on video monitor) image misalignment, adjust the set screws (10) to
produce the desired effect. (Note: When adjusting the set screws, loosen one and tighten the opposite
one.) After accomplishing the alignment of the two images, gently tighten the three socket head cap
screws on the prism bracket. Watch the video image as the screws are tightened to ensure that the
images stay aligned.
