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 8. (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.
