2. Emission points.
A steady or fluctuating pinpoint of bright light in the image area

and does not go away when all light is blocked from the objective

lens of the monocular (Figure 5-3). The position of an emission

point within the image area does not move. Not all emission

points make the ATN NVM-14 rejectable. Make sure any emis-

sion point is not simply a point light source in the scene you are

viewing. Emission points are acceptable if they do not interfere

with the ability to perform the mission.

3. Black Spots.
These are cosmetic blemishes in the image intensifier or dirt or

debris between the lenses. Black spots are acceptable as long

as they do not interfere with viewing the image.

No action is

required if this condition is present unless the spots inter-

fere with the operator’s ability to perform the mission.
