A. Bright Spots.
a bright spot is a small, non-uniform, bright area that may flicker or
appear constant (Figure 3-3).
Not all bright spots make the atN NVG-7 rejectable. Cup your hand
over the lenses to block out all light. If the bright spot remains, re-
turn the atN NVG-7. Bright spots usually go away when the light is
blocked out. make sure any bright spot is not simply a bright area in
the scene you are viewing. Bright spots are acceptable if they do
not interfere with the ability to view the outside scene.
B. 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 lenses
of the bi-ocular (Figure 3-3). the position of an emission point within
the image area does not move. Not all emission points make the
atN NVG-7 rejectable. make sure any emission 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 usability of the
device.
