5.1.5 Aiming and Focusing

Once you have the sensor in place, you need to aim and focus it on the target. To aim and focus the
sensor, complete the following:
1. Loosen the nuts or bolts of the mounting base. (This can be either a factory-supplied accessory
or customer-supplied base.)
2. Look through the eyepiece and position the sensor so the target is centered as much as possible
in the middle of the reticle, see Figure 10. (Note that the target appears upside down.)
3. Turn the lens holder clockwise or counter-clockwise until the target is in focus. You can tell the
lens is focused correctly by moving your eye from side to side while looking through the
eyepiece. The target should not move with respect to the reticle. If it does, keep adjusting the
focus until no apparent motion is observed.
4. Check again to be sure the target is still centered, and secure the mounting base. Focusing is
complete.
When focusing the sensor, do not depend on the clarity of the image through the
eyepiece to determine the focus. Use the "move the eye" technique described in step 3
above. If the desired focus distance is known in advance, this focusing can be
conveniently done in the office environment before installation.
